Progressive Crushing of Polymer Matrix Composite Tubular …
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 ...
