Particle modeling of dynamic fragmentation

Hybrid Lattice Particle modeling (HLPM) introduces a novel method for analyzing dynamic fragmentation of materials under extreme conditions like high-speed impacts. By integrating particle modeling with conventional lattice theory, it treats materials as discrete assemblies without focusing on particle size. The model utilizes various interaction potentials and maps spring constants to a lattice system, aligning with material properties. HLPM stands out for its ease of input preparation, computational efficiency, post-fracture simulation capabilities, and multiscale modeling advantages.
