显示更多 [+] 显示较少 [-]Research on fracture in HY-100 steel under mixed mode (Modes I and II), dynamic, elastic-plastic loading conditions is described. A combined experimental and finite element analysis effort was pursued. The analysis employed the J criterion for fracture; a criterion which effectively generalizes the conventional J-integral to mixed mode and dynamic loading conditions. The experiments were performed with inclined-notch three-point-bend specimens of HY- 100 steel. By coupling the experiments and finite element analyses, a fracture criterion based on a critical J value was devised and verified.
