Dynamic Plastic Fracture
塑性动态断裂实验研究

Dynamic plastic fracture properties of ductile material under explosive loading are tested. In our experiments the following properties are measured: a)The crack propagation procedure and its speed in plastic flow field; b)The dynamic plastic fracture toughness CTOD and its variation with different. crack propagation speeds. In addition, micro-analyses arc also made for specimen fractures corresponding to different crack propagation speeds.
