FE-Investigation on Caustics for Measuring Impact Fracture Toughness,ads is considered and caustics in reflection are generated by making assumption of plane stress condition. The crack is assumed to begin to propagate when the theoretically exact value of K.(t) reaches a critical value K.. The time history of the “measured” dynamic stress intensity factor K.(t) is d

The Transient Analysis of a Subsurface Inclined Crack Subjected to Stress Wave Loading,is studied. The realistic impact loading is simulated by a Sine function with a duration period. The solutions are determined by linear superposition of the Green function obtained by Tsai and Ma [1]. The exact closed form solutions of stress intensity factor histories are obtained. These solutions
