Study of post-impact behaviour of thin hybrid carbon/epoxy and glass/epoxy woven composite laminates under fatigue tensile loading – Part II: Numerical study

This article concerns the modelling of post-impact damage propagation in thin carbon/epoxy and glass/epoxy hybrid woven composite laminates loaded fatigue tension. The is based on semi-continuous approach implemented into explicit finite element code RADIOSS. bundles are modelled with rod elements resin modeled a specific damageable shell element, used to stabilize bundles. extended tensile loadings. Resin damaging for through two laws Yxy-Nresina Yxy-Nresinb thermodynamical forces identified experimental results obtained Part I. Fiber breakage introduced Basquin curves compressive strains. accumulation taken account by Miner’s rule. For several impact energies amplitude loading, well correlates terms scenario, path speed.
