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 K_ID, 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 K_ID and ȧ.
