摘要：

This paper addresses the task of using a commercial non-linear Finite Element code as a design tool to simulate (and design) the behaviour and performance of laminated composite structures. It is shown that the need to model the stress field ahead of a crack tip, in a tiny 'cohesive zone', does not necessarily mean having to use tiny finite elements.
