抄録

A computational procedure is presented for evaluating the dynamic stress intensity factors for compact tension (CT) and bend specimens under impact loading conditions. The dynamic stress intensity factors for the specimens subjected to arbitrary impact loads can be computed by super-imposing the step-impact response functions. The response functions for CT and bend specimens are obtained by the finite element method. The recent dynamic fracture tests indicate that a loss of contact between the bend specimen and the anvils occurs during the impact loading. The present procedure is effective for the determination of the dynamic stress intensity factors for the specimens, even if the loss of contact occurs.
