Abstract

Dynamic fracture behavior of PMMA was studied using the method of caustics in combination with a Cranz-Schardin high-speed camera. Single-edge-cracked tensile specimens were fractured under pin-loading conditions so that cracks could undergo acceleration and deceleration stages in one fracture event. To study the effect of the loading positions, dynamic stress intensity factor K_ID, crack velocity a• and load P applied to the specimens were determined in the course of crack propagation. Unloading rate P•, time derivative of P, was also evaluated to correlate with the time histories of K_ID and a•.
