Load bearing interface design for a pan-tilt mechanism for severe marine environments
… two-axis (pan and tilt) machine. Vibration and shock testing induced failure in the interface between the payload and the tilt shaft, through which the control cabling connected to the sensors, taking the system out of service and creating a hazard for Sailors. This thesis proposes a tapered, …

Cycling studies of micro-tubular solid oxide fuel cells
… were observed. Lastly, thermal and electrical shock test were performed. The critical fracture temperature (ΔTC) was established by thermal shock at approximately 180⁰C. Under electrical shock testing, the tubes were found to fail after 13 – 15 electrical shock cycles, depending on the shock …
