A Finite Element Method For Geometrically Nonlinear Large Displacement Problems In Thin, Elastic Plates And Shells, Ronald August Melliere
A Finite Element Method For Geometrically Nonlinear Large Displacement Problems In Thin, Elastic Plates And Shells, Ronald August Melliere
Doctoral Dissertations
"A finite element method is presented for geometrically nonlinear large displacement problems in thin, elastic plates and shells of arbitrary shape and boundary conditions subject to externally applied concentrated or distributed loading. The initially flat plate or curved shell is idealized as an assemblage of flat, triangular plate, finite elements representing both membrane and flexural properties. The 'geometrical' stiffness of the resulting eighteen degree-of-freedom triangular element is derived from a purely geometrical standpoint. This stiffness in conjunction with the standard small displacement 'elastic' stiffness is used in the linear-incremental approach to obtain numerical solutions to the large displacement problem. Only …
A Comparison Of Lumped Parameter Models Commonly Used To Describe One-Dimensional Vibration Problems, Suresh Kumar Tolani
A Comparison Of Lumped Parameter Models Commonly Used To Describe One-Dimensional Vibration Problems, Suresh Kumar Tolani
Masters Theses
"Three lumped parameter model representations of the one-dimensional uniform continuous system in a vibration state are examined. The exact (continuous) solutions were used as a reference to evaluate the accuracy of the results obtained via these discrete element models. The model comparisons, carried out for both the principal modes and the systems under forced excitations, are based on the maximum strain energy. The effect of varying the number of segments in the model representation showed improvement in approximating the exact strain energy solution as the number of segments was increased. In general, the results of the model comparisons based on …
The Analysis Of R-S-S-R Spatial Four-Bar Mechanism, David Perng Chyi
The Analysis Of R-S-S-R Spatial Four-Bar Mechanism, David Perng Chyi
Masters Theses
"Although many methods are known for the kinematic analysis of spatial mechanisms, such as descriptive geometry, vector analysis, dual number theory, matrices, screw calculus, and various other methods, a better way to analyze the specific R-S-S-R four-bar mechanism is to use tensor methods in order to eliminate the apparently formidable and tedious tasks of mathematically formulating problems and obtaining solutions. The analysis described in this paper is developed basically by using tensor notations and operations, and the calculations take advantage of the capabilities of modern digital computers. A FORTRAN program for the IBM 360 Data Processing System which will analyze …
The Use Of Turbulence Energy Equation In Boundary Layer Study, Ro-Chi Tai
The Use Of Turbulence Energy Equation In Boundary Layer Study, Ro-Chi Tai
Masters Theses
"A turbulent boundary layer problem has been studied analytically and compared with an available experiment in the literature. Correlations of the experimental data were made to investigate the validity of the commonly used empirical relations on turbulent shear stresses. It was found that the model which related the local turbulent shear stress linearly with the local turbulent kinetic energy, as used by Bradshow et. al., appeared to be most reasonable. combining this model with the expression of turbulent viscosity given by Boussinesq, it was then possible to introduce the turbulence-energy equation in addition to the governing equations of continuity and …

Design Of R-C-C-R Spatial Mechanism, Kao-Chien Hsei
Masters Theses
"An analysis to design a particular R-C-C-R spatial mechanism was developed using tensor notations and operations. This specific R-C-C-R spatial mechanism can be used to couple two shafts intersected at a skew angle with constant rotating speed ratio. This skew angle, or bending angle of the two shaft, may vary from 30 up to 180 degrees. The governing equations of relative positions of the mechanism were formulated as a function of two variables: the bending angle of the shafts and the rotating angle of the input link. To exemplify the various design conditions, the design parameter versus the bending angle …
Investigation Of Free Convection Heat Transfer From An Inclined Flat Plate, Phairojna Sang-Urai
Investigation Of Free Convection Heat Transfer From An Inclined Flat Plate, Phairojna Sang-Urai
Masters Theses
"The experimental investigation was conducted to determine temperature distribution and convective heat transfer coefficients in terms of Nusselt number for an inclined heated flat plate in air. The heated surface of the aluminum flat plate was set facing upward and moved through seven positions from the vertical to the horizontal. The investigation shows that the local Nusselt number can be predicted by Kiekus's solution within 12 per cent for inclination angles from the vertical through 75° from the vertical. In the case of the vertical position, Eckert's solution gives a better prediction. For the horizontal position the results show good …
Mutually Dependent Heat And Mass Transfer In Laminar Duct Flow, E. M. Sparrow, T. S. Chen
Mutually Dependent Heat And Mass Transfer In Laminar Duct Flow, E. M. Sparrow, T. S. Chen
Mechanical and Aerospace Engineering Faculty Research & Creative Works
An analysis is performed of the strongly coupled heat and mass transfer processes which result from sublimation of mass from the walls of a duct into a flowing gas, the latent heat being provided solely by convective transfer from the gas. The flow is assumed to be laminar and hydrodynamically developed. Results are given for the stream ward variations of the bulk and wall temperatures and mass fractions, of the heat and mass transfer rates, and of the local heat transfer coefficient. Representative temperature and mass fraction profiles are also presented. Entrance lengths characterizing the near approach to fully developed …
Apparatus And Techniques For The Plane Wave Analysis Of Acoustic Filters, Victor Hugo Simon
Apparatus And Techniques For The Plane Wave Analysis Of Acoustic Filters, Victor Hugo Simon
Masters Theses
"This thesis describes a method for determining the reflection and transmission characteristics of acoustic filters under static (i.e. no flow) conditions. These characteristics are obtained by the combination of linear plane wave acoustic theory with a sequential experimental procedure. The experimental data necessary for the calculation of the reflection characteristics were obtained from measurements made on the inlet side of the filter with a standing wave tube apparatus. In order to calculate the transmission characteristics of the filter, the standing wave measurements were augmented with measurements taken on both the inlet and outlet side of the filter. This was accomplished …

Film Boiling Heat Transfer From An Oscillating Sphere, L. G. Rhea, R. G. Nevins
Mechanical and Aerospace Engineering Faculty Research & Creative Works
An experimental investigation has been undertaken to determine the effect of oscillation of the heat transfer surface on turbulent film boiling heat transfer. A transient technique was used to calculate the heat flux from copper spheres of 1 in., 3/4 in., and 1/2 in. dia. In all tests, saturated liquid nitrogen at atmospheric pressure was used as the boiling fluid. The data obtained were found to be in good agreement with published theory at zero frequency. The range of frequencies studied was from zero to approximately 12 cps at peak-to-peak amplitudes of 2 in. and 1 in., i.e., at amplitude-to-diameter …

The investigations of this study are concerned with: (1) the physical processes that occur in the precursor and in the nonequilibrium region behind a strong shock wave during its approach to equilibrium in an argon like gas; (2) the influence of different atom-atom collisional rates in the relaxation region on the precursor; and (3) the cause of precursor ionization, which in this study has been assumed to be the photoionization of both the ground and excited states. The argon like gas is regarded as a combination of two gases: one consisting of electrons and the other of atoms and ions. …
Experimental Determination Of Dynamic Properties Of Aluminum Including Poisson's Ratio, Terry Lee Holman
Experimental Determination Of Dynamic Properties Of Aluminum Including Poisson's Ratio, Terry Lee Holman
Masters Theses
"Two rods of 7075-T651 aluminum are longitudinally impacted to investigate the material's dynamic properties. The test rod, initially at rest, is instrumented with strain gages to record the strain-time history after the impact rod, accelerated to uniform velocity by an air gun launcher, strikes the test rod. A camera records the strain-time pattern displayed on an oscilloscope. The experiment indicates a consistent rise time of approximately 9 µsec. Simple one-dimensional theory correlates well with the experimental data. Compensation is included for the transverse sensitivity of the gages used. The dynamic values for both the modulus of elasticity and Poisson's ratio …
