Sublaminate Damage Mechanisms in Composite Structures.

Abstract

This final report summarizes the objectives and accomplishments of research on sublaminate damage mechanisms in composite structures. It may be separated into three elements. The first is interlaminar fracture analysis methodology development. Existing methods for predicting strain energy release rate components have been assessed, and two new alternative approaches have been developed and illustrated. The second is the creation of a phenomenologically based criterion for damage tolerance analysis of composite structures. An equivalent damage parameter and a relevant compliance measure are determined from experiments. This methodology has been validated by seven independent experiments. Keywords: Delamination, Damage tolerance, Damage in composites, Composite materials.
