Abstract
A two-part study was conducted to compare the yielding, plastic flow, and fracture behavior of two implantable grades of UHMWPE (GUR 1120 vs 4150 HP). The first part explored the hypothesis that up to the polymer yield point, the monotonic loading behavior of UHMWPE displays similar true stress-strain behavior in tension and compression. Through uniaxial tension and compression tests, the equivalent true stress was compared to the strain response of UHMWPE up to 0.12 true strain. In the second part of the study, the ultimate true stress and strain for UHMWPE were determined and the fracture surfaces after failure were characterized.
