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 KID, 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 KID and a•.
