Publication: Veryst develops advanced constitutive model for UHMWPE

April 1, 2010
Ultra-high molecular weight polyethylene (UHMWPE) is used extensively in biomedical devices due to its mechanical properties, including high impact and wear resistance. Veryst developed an advanced thermomechanical constitutive model for UHWMPE where the microstructure of the material is represented using three structural domains that capture the experimentally-observed, nonlinear, time- and temperature-dependent response at small and large strains.
