Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma Oct 2013

Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma

The Summer Undergraduate Research Fellowship (SURF) Symposium

Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …


Insights Into The Effect Of Geometrical Parameters In The Mechanical Properties Of The Radular Teeth Of The Cryptochiton Stelleri – A 3d Print Approach, Chan Jeong, Enrique Escobar, Pablo Zavattieri Dr. Oct 2013

Insights Into The Effect Of Geometrical Parameters In The Mechanical Properties Of The Radular Teeth Of The Cryptochiton Stelleri – A 3d Print Approach, Chan Jeong, Enrique Escobar, Pablo Zavattieri Dr.

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Cryptochiton Stelleri is known to have ultra-hard radular teeth that have one of the largest hardness (9-12GPa) and stiffness (90-125GPa) among other biological materials such as Enamel and Abalone shell. The ultrastructure of the teeth is formed by a bundle of highly mineralized rods composed of iron oxides and organic material. The main method to measure the material properties has been through nanoindentation. However there are limitations to nanoindentation of the Chiton’s teeth such as limited equipment, costly and time consuming preparation of the samples, and observation of nanoscale features being difficult. In this work, the rod-like microstructure of …


Transient And Quasi-Steady Thermal Behaviour Of A Building Envelope Due To Retrofitted Cavity Wall And Ceiling Insulation, Aimee Byrne, Gerard Byrne, Anna Davies, Anthony Robinson Jan 2013

Transient And Quasi-Steady Thermal Behaviour Of A Building Envelope Due To Retrofitted Cavity Wall And Ceiling Insulation, Aimee Byrne, Gerard Byrne, Anna Davies, Anthony Robinson

Articles

Accurate understanding of the thermal behaviour of building components is essential for predicting heat-ing or cooling needs and facilitates the implementation of more successful energy saving strategies and retrofits. This paper focuses on a specific measure commonly introduced through the residential energy efficiency retrofit programmes in Ireland–insulation. Traditionally, assessments of the performance of building envelopes have been based on assumed thermal resistances of the materials involved, labora-tory tests and computer modelling. The aim of the present work is to investigate the in situ thermal behaviour of a case study building and its components under transient and quasi-steady environmental conditions, comparing …
