An Interrupted Dynamic Tensile Testing for Pure Copper Bars
interrupted tension high strain rate constitutive model necking void evolution pure copper bar
2012/9/24
A high-speed tensile fac ility (HSTF) invented by us was applied to interrupt tests for pure copper bars controlled locally at different levels of elongatio n. It was realized to isolate and identify ...
