Application of Dynamic Fracture Mechanics Concepts to Composites: Final Report 2000

Abstract

This report summarizes the work completed in the months of June 1996 - December 1999 for the principal investigator's Young Investigator Program grant. As such, the report represents a final summary of work, organized as follows. First, in a brief summary chapter, a review of the accomplishments of the work supported from June 1996 to December 1999 is given providing an overview of the successes during that period. Next, two chapters giving details of new work during the six months since the last annual report are presented. In these results, an experimentally useful solution for the stress intensity factor history at the comer of an impacting punch is derived for isotropic and orthotropic materials. Then that solution is compared to experimental measurements of the stress intensity factor history at the comer of an impacting punch in both isotropic and anisotropic materials. Good agreement between model and experiments is seen.
