Abstract
Dynamic fracture behavior of PMMA was studied using the method of caustics. Single-edge-cracked tensile specimens were pin-loaded so that cracks could undergo both the acceleration and deceleration process in one fracture event. The effect of loading position H1 was examined measuring the stress intensity factor KID, crack velocity ȧ and load P as a function of time t. Unloading rate Ṗ, time derivative of P, was also evaluated to investigate for a correlation with the time variations of KID and ȧ.
