Dynamic Crack Growth in Polymers,
Abstract
Over the past several years, considerable effort has been directed towards developing two-dimensional, finite-element computer codes to predict crack propagation behavior in large structures. One of the input parameters to these computer codes is the relationship between the crack extension force (or the stress intensity factor) and the velocity of crack propagation in the material. Experimental investigations of the dynamic behavior of crack propagation and arrest in several different polymers, epoxies, and structural steels have been conducted. This paper summarizes briefly the highlights of the work performed at the University of Maryland over the period 1972-1982 using dynamic photoelasticity, high speed multi-flash photography, and finite element modeling to study crack propagation.
