In this study, cross-linked poly-vinyl chloride (PVC) closed-cell foams were examined under quasi-static and high strain rate compression loading using a servo-hydraulic testing machine and a modified Split Hopkinson Pressure Bar (SHPB) apparatus consisting of polycarbonate bars for strain rates up to 1400 s~(-1). Three foam densities were examined viz. 75, 130, and 300 kg/m~3. Each core density has been subjected to various strain rates at both room and elevated temperatures. The stress-strain behavior was evaluated. A post impact study was also performed to evaluate the failure modes of the foam cores. When moving from room to elevated temperatures at high strain loading a reverse trend in failure modes was observed, which was not found in quasi-static testing at elevated temperatures.
