Faculty of Engineering - Papers (Archive)
There is relatively little numerical study on the behavior of eccentrically loaded high strength rectangular concrete-filled steel tubular (CFST) slender beam-columns with large depth-to-thickness ratios, which may undergo local and global buckling. This paper presents a multi scale numerical model for simulating the interaction local and global buckling behavior of hlgh strength thin-walled rectangular CFST slender beam-columns under eccentric loading. The effects of progressive local buckling are taken into account in the mesoscale model based on fiber element formulations. Computational algorithms based on the Muller's method are developed to obtain complete load-deflection responses of CFST slender beam-columns at the macroscale …

This paper presents a numerical simulation of the bearing reinforcement earth wall by PLAXIS 2D. The bearing reinforcement was regarded as a cost-effective earth reinforcement. The model parameters for the simulation were obtained from the conventional laboratory tests and back analyses from the laboratory pullout tests of the bearing reinforcement. The simplified method for modeling the bearing reinforcement, which converts the contribution of friction and bearing resistance to the equivalent friction resistance, is introduced. This method is considered to be acceptable and practical in working state with sufficient factor of safety and small pullout displacement. The bearing reinforcement is modeled …

Electroactive polymer (EAP) actuators have been attracting the attention of researchers due to their muscle-like behaviour and unusual properties. Several modelling methods have been proposed to understand their mechanical, chemical, electrical behaviours or ‘electro-chemo-mechanical’ behaviour. However, estimating the whole shape or configuration of the EAP actuators has always been challenging due to their highly non-linear bending behaviour. This paper reports on an effective method to estimate the whole shape deflection of the EAP actuators by employing a so-called backbone approach. Tri-layer configured polypyrrole (PPy) based EAP actuators were used as a soft and smart structure with more degrees of freedom …

Faculty of Engineering - Papers (Archive)
Change management is critical and challenging in the context of service-oriented computing paradigm when multiple services are supported by a single business process [1]. The complex dependencies between services and business processes have not been carefully investigated in the existing work. In particular, it is still lacking of an effective tool to support change impact analysis for coupled services and business processes. In this demo, we present a tool: Service Change Analyzer (SCA) for enabling impact analysis when a change happens. The SCA is built up based on our previous work for change analysis, in which a service-oriented business process …

Analysis Of Bloated Droplet Theory Using Steelmaking Process Models, N Dogan, G A. Brooks, M A. Rhamdhani
Faculty of Engineering - Papers (Archive)
There is significant evidence that droplets generated in steelmaking "bloat" due to the inability of gas generated from the decarburisation reaction to escape from the surface of liquid metal droplets. A model to describe this behavior was developed by Brooks, Subagyo, Coley and Pan based on their own experimental work and calculations and previous studies by Fruehan and co-workers. This approach has been successfully incorporated into an overall process model of oxygen steelmaking. A unique feature of this model is an evaluation of the decarburization kinetics of individual metal droplets in the emulsion and comparing this to the overall kinetics …

Cogging Force Analysis Of A Slotless Tubular Linear Motor With Finite Stator, Philip A. Commins, Jeffrey W. Moscrop, Christopher D. Cook
Faculty of Engineering - Papers (Archive)
Permanent magnet tubular linear motors have shown potential for use as direct drives in high precision applications such as machine tools. These devices have the ability to overcome or reduce many of the fundamental mechanical properties that limit the precision performance of traditional rotary to linear translation mechanisms, such as the ball screw. However, the cogging of the motor must be minimised for high precision applications. Previous work has assumed an infinite stator length, but this approach has limitations. This paper investigates the cogging force of a slotless tubular motor with a stator of finite length using finite element analysis. …

Seismic History Analysis Of Asymmetrical Adjacent Buildings With Soil-Structure Interaction Consideration, Mehmet Uz, Muhammad N. S Hadi
Faculty of Engineering - Papers (Archive)
The seismic response history analysis of multi-storey asymmetric adjacent buildings with soil-structure interaction (SSI) during impact is investigated in this study. The coupled multi-degree of freedom modal differential equations of motion for the two way asymmetric shear buildings are derived and solved using a step by step solution by the fourth-order Runge-Kutta method with impact and without impact. The SSI forces are modelled in the form of the frequencyindependent soil springs and dashpots. A numerical example of two-way asymmetric four-storey adjacent buildings under the variation of the important SSI system parameters such as the large and small SSI effects is …
Vertical Drain Consolidation Analysis In One, Two And Three Dimensions, Rohan T. Walker
Vertical Drain Consolidation Analysis In One, Two And Three Dimensions, Rohan T. Walker
Faculty of Engineering - Papers (Archive)
A new method, the g or 'eta' method, for modeling consolidation by vertical and horizontal drains is presented. The approach is applicable in one, two and three dimensional as well as axisymmetric cases. Material and geometry properties are familiar from unit cell vertical drain analysis and are consistent across dimensions. An uncoupled finite element method (FEM) program is used to test the efficacy of the new approach. Because drains are not explicitly modeled in the finite element mesh, mesh complexity and computational time are greatly reduced. Unlike existing plane strain matching methods there is no special transformation of permeability or …

Flac3d Analysis On Soil Moving Through Piles, E H. Ghee, W D. Guo
Faculty of Engineering - Papers (Archive)
Piles may be utilized as deep foundations or employed to support offshore structures, which may be subjected to passive loading due to lateral soil movements. The safety of the piled foundations depends on the additional stresses induced. This issue has been investigated recently by conducting model tests on single piles and on pile groups with a new apparatus developed by the authors. Typical test results were analysed and reported previously. In this paper three-dimensional finite difference analyses are reported: (1) to predict the results of two model tests (with and without axial load); and (2) to investigate the effect of …

General Probability Distribution-Based Qos Analysis For Web Service Composition, Huiyuan Zheng, Jian Yang, Weiliang Zhao
Faculty of Engineering - Papers (Archive)
In this paper, we propose a comprehensive solution for QoS aggregation in service composition. Different from existing work on QoS modeling which uses single values, discrete values with frequencies, or well known statistical distributions, the proposed method can work on QoS represented by general probability distributions. A set of formulas are developed to calculate the QoS probability distribution for the composite service based on the four identified patterns. Experimental results are provided to demonstrate the effectiveness of the proposed method.

In this paper, the free strain radial consolidation theory incorporating the changes of compressibility and permeability of the soil with the change in effective stress via time dependent surcharge preloading is presented. In contrast to the conventional analysis, the current study highlights the nonlinear characteristics of the soil during the consolidation process. A comparison of the nonlinear radial consolidation model, with the conventional theory and the equal strain theory i.e. constant volume compressibility, mv and constant coefficient of horizontal permeability, kh is presented. Finally, a case history at Muar coastal plain, Malaysia is analysed on the basis of the current …
Stress Analysis In Failed Roof At A Longwall Face, Jan Anton Nemcik, Ian Porter, Buddhima Indraratna
Stress Analysis In Failed Roof At A Longwall Face, Jan Anton Nemcik, Ian Porter, Buddhima Indraratna
Faculty of Engineering - Papers (Archive)
This paper presents a conceptual work on roof failure mechanisms at a longwall coal mining face based on a multiple sliding block model. Underground observations of the caved roof strata at the longwall face indicate that many types of fracture exist and that two are dominant. In response to roof convergence close to the goaf, the stratified ground flexes resulting in shear failure along the weak bedding planes that are present in sedimentary strata, while sub-vertical fractures form just ahead of the longwall face in response to the mining induced stress state. . These mining induced fractures usually occur at …

Faculty of Engineering - Papers (Archive)
In this paper, the mechanics of strip edge cracks and its propagation has been studied, and the effects of strip edge drop and stress intensity factor (SIF) on edge crack defections during cold rolling of thin strip have been discussed. An experimental investigation was presented into the effect of strip edge drop on edge cracks during cold rolling of thin strip. The edge crack increases significantly due to more inhomogeneous deformation and work hardening at the strip edge. The effective stress intensity factor range is important as it represents the major physical cause of the crack propagation. The efficiency and …

A Boundary Element Analysis On The Influence Of Krc And E/D On The Performance Of Cyclically Loaded Single Pile In Clay, Sudip Basack
Faculty of Engineering - Papers (Archive)
The environment prevalent in oceans necessitates the piles supporting offshore structures to be designed against lateral cyclic loading initiated by wave action. Such quasi-static load reversal induces deterioration in the strength and stiffness of the soil-pile system, introducing progressive reduction in the bearing capacity associated with increased settlement of the pile foundation. To understand the effect of lateral cyclic load on axial response of single piles in soft clay, a numerical model was previously developed and validated by the author. Using the methodology, further analysis has been carried out to investigate how the variation in relative pilesoil stiffness and eccentricity …

In an ongoing research project focusing on improving learning in first year engineering mechanics, a framework for engineering mechanics knowledge has been identified. The framework has been applied to break down and categorise common mistakes made by students at four separate institutions to find out where students are struggling in their efforts to learn statics and dynamics. The framework separates knowledge into factual, procedural, conceptual, and principle areas in a semi hierarchical manner. In using this framework, it has become clearly evident that the marks students are awarded for their work tend to be biased towards procedural knowledge, rather than …

A mathematical model has been developed considering the influence of surface tension on the blowing number (NB) using plant data from the study of Holappa and Jalkanen. The model predicts the droplet formation as a function of carbon, sulphur and oxygen contents in the metal, the temperature profile of the metal bath and lance height. This study includes a sensitivity analysis to investigate the …

Analysis Of Fume Formation Rate And Fume Particle Composition For Gas Metal Arc Welding (Gmaw) Of Plain Carbon Steel Using Different Shielding Gas Compositions, Kristin R. Carpenter, Brian J. Monaghan, John Norrish
Faculty of Engineering - Papers (Archive)
The present paper compares thirteen shielding gases and their impact on FFR and fume particle while welding in the spray transfer regime. There was no obvious influence from the shielding gas on particle composition and fume particles were identified as (Fe,Mn)3O4. There was a slight peak shift that indicated that small levels of Mn, as detected by TEM-EDS, substituted for Fe in the Fe3O4 phase. Shielding gas composition is an important parameter for successful gas metal arc welding (GMAW) and has been shown to affect the fume formation rate (FFR). In Ar-based mixtures, increasing CO2 had a greater impact than …

The fatigue properties of multiphase steels are an important consideration in the automotive industry. The different microstructural phases present in these steels can influence the strain life and cyclic stabilized strength of the material due to the way in which these phases accommodate the applied cyclic strain. Fully reversed strain-controlled low-cycle fatigue tests have been used to determine the mechanical fatigue performance of a dual-phase (DP) 590 and transformation-induced plasticity (TRIP) 780 steel, with transmission electron microscopy (TEM) used to examine the deformed microstructures. It is shown that the higher strain life and cyclic stabilized strength of the TRIP steel …

Consolidation Analysis Of A Stratified Soil With Vertical And Horizontal Drainage Using The Spectral Method, Rohan Walker, Buddhima Indraratna
Faculty of Engineering - Papers (Archive)
A novel use of the spectral method to determine excess pore water pressure during vertical consolidation of multi-layered soil with time constant material properties is presented, considering a unit cell with combined vertical and radial drainage. Equal strain conditions are assumed in the analysis. The novel adoption of material properties that vary in a linear fashion with depth allows arbitrary distributions of properties to be modelled. By incorporating surcharge and vacuum loading that vary with both depth and time, a wide range of consolidation problems can be analysed. The spectral method is a meshless approach producing a series solution to …

Faculty of Engineering - Papers (Archive)
The quality of service (QoS) is a major concern in the design and management of Web service composition. Existing methods for QoS calculation either do not take the probability of path execution into consideration when QoSs are provided for different execution paths, or do not take different execution paths into consideration when a single integrated QoS is provided for the whole composition. In this paper, a comprehensive QoS analysis approach is proposed that calculates the QoS probability distribution by considering both the execution probability and execution conditions of each path in the service composition. Four types of basic composition patterns …

Validation Of Particle Flow Through A Conveyor Transfer Hood Via Particle Velocity Analysis, David B. Hastie, Andrew P. Grima, Peter W. Wypych
Faculty of Engineering - Papers (Archive)
A critical factor in the design of conveyor transfers is the ability for material to flow at a velocity as close to that of the conveyor belt as possible. If particle velocity increases too much issues such as particle attrition, dust generation, chute wear and excessive noise can arise, whereas if particle velocity were to decrease, stagnation zones could develop, resulting in issues such as spillage or chute blockage. There are numerous methods available in which to analyse particle flow through a conveyor transfer, including; continuum based analytical methods, the discrete element method (DEM) and experimental analysis. This paper will …
