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.
Dr. Sean Teller spoke about "Impact Testing and Modeling of Energy Absorbing Foams for Finite Element Simulation" at the Foam Expo 2017. His presentation focused on high strain-rate testing and modeling of foams for use in finite element simulations.
Dr. Mark Oliver participated in the “Additive Manufacturing: Design, Test, and 3D Print for Production” session at ANTEC 2018, and Dr. Sean Teller participated in the “Engineering Properties and Structure: Innovations in Polyolefins and Plastics” session.
Dr. Stuart Brown spoke about “Modeling and Design of Reinforced Elastomeric Products for Oil and Gas Applications” and “High Strain Rate Testing of Polymers for Impact Simulations,” while Eric Schmitt spoke about “Calibration and Experimental Validation of Advanced Constitutive Models of Polymeric Materials at High Strain Rates.”
