2015-12-14  In crushing situations, composites and metals behave very di fferently. While metals absorb energy by plastic deformation, the process of crushing in composites is more complex. Composites are often constituted by layers and these tend to separate during the crushing (delamination); on the other hand, in each one of

Progressive Crushing of Polymer Matrix Composite

Composite material progressive crushing with micro-fragmentation, associated with high crush energy, is designated as mode-Ι. Progressive failure mode is classified by the progressive end-crushing with splaying of the laminate tube starting at one end of the specimen. This causes the tube to form continuous fronds which spread outwards and inwards.
