Failure mechanisms in twill-weave laminates: FEM predictions vs. experiments

The mechanics of woven fabric-based laminated composites is complex, but computational models can contribute to its enhanced understanding. In this work the architecture of a twill-weave graphite epoxy laminate was characterized experimentally by microscopy of polished sections. The mechanical response under tensile loading was then investigated and a microscopic assessement of the failure mechanisms was conducted. The finite element approach...
