Progressive failure analysis of 2D woven composites at the meso-micro scale
TL;DR: In this paper, a multi-scale progressive damage modeling strategy was proposed to investigate the damage and failure behaviors of 2D woven composites, and the damage evolution is governed by the material fracture energy during failure.
