Abstract
Understanding the interaction between munition and target is necessary for the optimization of the performance of both the target and the penetrator. Commercially available technoUnderstanding the interaction between munition and target is necessary for the optimization of the performance of both the target and the penetrator. Commercially available technology for the numerical simulation of ballistic penetration and shaped charges falls short of being able to reliably simulate damage to armors, runways, surface and buried concrete bunkers and other hardened underground targets. Our Lagrangian finite element based approach, with continuous adaptive remeshing, gives us the possibility of accurately simulating problems involving large deformations and fragmentation. Thermomechancial coupled models of models of brittle and ductile materials, cohesive material interfaces for layered material and contact algorithms able to solve complex multi-body contact situations, e.g. in fragmentation, are key pieced in our simulation package for impact penetration. logy for the numerical simulation of ballistic penetration and shaped charges falls short of being able to reliably simulate damage to armors, runways, surface and buried concrete bunkers and other hardened underground targets.
