High strain-rate compression experiments were performed with a split-Hopkinson pressure bar (SHPB) at 500–4000/s on cylindrical samples of a Zr-based bulk metallic glass (LM-1) in both the fully amorphous and annealed conditions. The effects of changes to the specimen geometry (i.e., L/D ratio) and the material heat treatment [i.e., annealing versus amorphous (as-received)], on the peak stress,...

The characterization of soft or low impedance materials is of increasing importance since these materials are commonly used in impact and energy absorbing applications. There is a need to measure the high-rate material properties of soft materials, where the mode of loading is predominantly compressive and large deformations may occur at high rates of deformation. Importantly, the competing eff...

In dynamic testing of concrete-like materials, there is a need in distinguishing structural effects from genuine strainrate effects. In this paper, this generic problem is studied by numerical simulations based on a phenomenological material model available in the commercial finite element (FE) code Abaqus. The numerical results show that the increase of the dynamic increase factor (DIF) with t...
