AbstractThis paper describes recent progress on numerical simulation of shaped charges (SC) using an Arbitrary-Lagrangian-Eluerian (ALE) framework. The framework consists of simulating the formation, elongation and possible fragmentation of the liner. The aforementioned stages of SC development were modeled using the ALE element formulation in the LS-DYNA Finite Element Analysis software. The simulation incorporates features such as Arbitrary-Lagrangian-Eulerian-Multi-Material-Group, the High Explosive Burn, the Johnson-Cook constitutive material model, and the Jones Wilkins-Lee and Mei-Gruneisen Equations-of-State. The model provides a robust means of handling the large amount of deformation present in SC jet formation and elongation. Results for a shaped charge with a 80-mm cone diameter are resented.
