Time Dependence in Fracture Mechanics of Adhesive Joints and Composites

Abstract

The research program covered in this report is concerned with understanding the time dependent effects involved in the failure of polymer based adhesive joints and in advanced composites. The emphasis is placed on: a) Examining the effect of time dependent processes that influence failure in bonded structures and in composites; b) Assessing the validity of currently used analytical techniques in predicting failure of adhesive bonds; and c) Examining means of accelerated testing which would allow one to make long-term failure predictions on the basis of the relatively short-term tests, under both monotonic and fatigue-type loading.
