Effect of the Stiffness of Ingerface Defect on Dynamic Interface Crack propagation

계면에 존재하는 결함의 강성도가 동적 계면균열전파에 미치는 영향

The dynamic photoelasticity with the aid of Cranz-Shardin type high speed camera system is utilized to record the dynamically propagating behavior of the interface crack. This paper investigates the effects of the stiffness of interface defect(exist along the path of the crack propagation) on the dynamic interface crack propagation behavior by comparing the experimental isochromatic fringes to the theoretical stress fields.
