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. Mark Oliver and Dr. Sean Teller will be presenting and the NAFEMS World Congress, taking place May 19-22 in Salzburg, Austria. Dr. Oliver will be presenting on “Techniques for Inverse Calibration of Cohesive Zone Models”. Dr. Teller will be presenting on “Rate and Pressure-Dependent Failure Modeling of Thermoplastics“.

Researchers studying the anatomical and mechanical properties of ovine ribs asked Veryst to conduct high strain rate testing on our custom-built drop tower.
Veryst is pleased to introduce Bachir Abeid. Abeid’s primary focus is on computational modeling. His experience includes a wide range of mechanical testing, modeling, simulation, prototyping, and product development.
Dr. Sean Teller has joined Veryst Engineering, bringing extensive experience in the mechanical behavior of materials at low and high strain rates, including viscoelasticity, viscoplasticity, nonlinear materials, and fracture mechanics.
