The aim of this project is to develop a unified predictive numerical model for high velocity impact phenomena, which would take into account simultaneously the fragmentation of the projectile and spalling/plugging fracture of the target.
The fragmentation of the projectile is obtained as a result of multiple crack growth, handled by the developed distance-based enriched meshfree method.
Plugging is handled through a coupled thermo-mechanical constitutive model, which predicts areas of high temperature associated with highly localized deformation.
Macro-cracks in spalling are handled with a meshfree scheme able to coalesce void growth and micro-cracks.
