Implementation of the Erosion Algorithm Under High-Strain Rate Conditions

An algorithm for erosive fracture of solid bodies during high-velocity interactions is presented. The algorithm is implemented using the finite element method. The proposed mechanism for describing erosive fracture and restructuring of the computational mesh ensures the conservation of mass law. To accelerate the data preparation for the erosive fracture algorithm, optimization of the algorithm for searching adjacent element faces has been performed.
