Dr. Sean Teller spoke about "Impact Testing and Modeling of Energy Absorbing Foams for Finite Element Simulation" at the Foam Expo, which took place February 28-March 2, 2017 in Novi, Michigan. His presentation focused on high strain-rate testing and modeling of foams for use in finite element (FE) simulations.
Polymer foams are complex materials that exhibit drastic changes in response to applied loading and strain rates and may show greater strain-rate dependence than bulk polymers. Quasi-static tests alone do not capture the material response or applied strain rates experienced during impact events, including automotive crashes, consumer electronic drops or athletic events. Accurately capturing the strain rate dependence of foams is critical to understanding the impact response and energy absorption properties of different foams. Dr. Teller discussed the high-strain-rate testing and material modeling capabilities Veryst Engineering has developed to characterize and implement models in commercial FE software.
