An Investigation of Using n-Si Piezoresistive Behavior to Develop a Three-Dimensional Stress Sensing Rosette
DownloadFall 2013
This work involves the design, microfabrication, calibration, and testing of a new silicon-based piezoresistive rosette capable of extracting the three-dimensional (3D) stresses in the silicon upon deformation. A new 10-element piezoresistive rosette was devised to extract all stress components...

Optimal Design of Coke Drum Skirt Slots and Analysis of Alternative Skirt Support Structures for Thermal-Mechanical Cyclic Loading
DownloadFall 2017
The skirt-to-shell attachment weld on coke drums is susceptible to low-cycle fatigue failure due to severe thermal-mechanical cyclic stresses. Therefore, various skirt attachment designs have been proposed and implemented to reduce stress and thus improve reliability. The most common skirt design...
