- 論文の詳細を見る
Dynamic crack propagation and unloading behaviors of epoxy and PMMA were studied using the method of caustics. Single-edge-cracked tensile specimens were pinloaded so that cracks could undergo both the acceleration and the deceleration process in one fracture event. The effect of loading position H_1 was examined by measuring the stress intensity factor K_<1D>, crack velocity a and load P as a function of time t. Unloading rate P, time derivative of P, was also evaluated to examine correlation with the time variations of K_<1D> and a. The results showed that H_1 was an important factor in the change of behaviors of K_<1D>, a, P and P.
