  Oxidative Degradation of UHMWPE in Retrieved Shoulder and Knee Implants

  This project studies how ultra-high-molecular-weight polyethylene (UHMWPE) components in joint implants oxidize over time after implantation. By analyzing retrieved shoulder and knee implants, the research quantifies oxidation levels, correlates them with mechanical damage such as wear, delamination, or cracking, and evaluates how design, sterilization method, and in vivo duration affect material degradation and performance.

• Fatigue of Ice

  Fatigue of Ice

  This project investigates how repeated or cyclic loading affects the strength and failure behavior of ice. By applying controlled stress cycles, the study examines the strength of ice over time. The goal is to understand how ice respond to cyclic loading and how factors such as temperature, grain structure, salinity, and loading frequency influence fatigue life.
