Numerical simulation of multi-hit impact on Ceramic/Composite armor

The numerical simulation of ballistic multi-hit impact on ceramic/composite armors is very challenging.The damage introduced by the previous hit affects the performance of the armor.In composite backings the damage is often more diffused than for metallic backings.

Moreover, different sources of damage can intervene within the composite material.The present work redwing viburnum proposes a mesoscopic scale approach to assess these issues.The 2D woven material is modelled with beams elements embedded in volume elements.

Each hastu goyal component has its own material constitutive law and its damaging law.This approach allows to better model the damaging of the material, but also to better identify the material parameters from a set of basic experiments.
