Compressive mechanical response of a low-density epoxy foam at various strain rates

We experimentally obtained compressive stress–strain response of a low-density epoxy foam at various strain rates. In particular, compressive stress–strain behavior at intermediate strain rates that has not been previously well understood were characterized by using a modified MTS and a split Hopkinson pressure bar (SHPB). Strain rate effects on the modulus of elasticity and cellcollapse stress for this low-density epoxy foam were determined.
