Dynamic compression of a zirconium-based bulk metallic glass confined by a stainless steel sleeve

Anvil-on-rod impact experiments were performed on zirconium-based bulk metallic glass rods with stainless steel confinement sleeves. High-speed photography and velocity interferometry were used to obtain qualitative and quantitative information about the transient deformation and failure response of the impacted specimens. Fracture surfaces of the recovered, impacted specimens were analyzed using scanning electron microscopy. Numerical simulations were also used to elucidate the deformation and failure response and better understand the effects of the altered stress states caused by the confinement sleeve.
