Monitoring Damage Characteristics in a Filled Elastomer under Cyclic Loading Using X-Ray Techniques

Abstract

In this study, the damage fields near the crack tip in edge-cracked sheet specimens subjected to a constant strain rate of 0.05 min-(exp -1) were investigated using real-time radiographic techniques. During the tests, Lockheed-Martin Advanced Technology Center's high-energy real-time x-ray system (HERTIS) was used to monitor damage initiation and evolution processes near the crack tip. The experimental findings indicate that x-ray technique is a promising technique to monitor damage evolution during crack propagation.
