LS-DYNA is a general-purpose transient dynamic finite element program capable of simulating complex real-world problems involving large deformations. LS-DYNA is the industry standard for analyzing structures subjected to short duration loads and significant geometric nonlinearities. Its capabilities include finite element Lagrangian simulations, fully Eulerian simulations, Arbitrary Lagrangian-Eulerian (ALE), coupled fluid-structure interaction (FSI), and Smoothed Particle Hydrodynamics (SPH). An extensive library of material models is available.

Protection Engineering Consultants uses LS-DYNA for design, analysis and simulation. PEC engineers regularly use it to predict armored vehicle response and injury predictions for blast threats, including buried land-mine detonation with SPH and ALE routines. We’ve also used LS-DYNA as a tool to support analysis and design for vehicle impacts into counter-mobility barriers, aircraft arresting systems and related material development, high rate behavior of energy-absorbent materials, acoustic measurement systems, locomotive collisions with shipping canisters for spent nuclear fuel, blast-loaded windows and frames, and progressive collapse in multi-story structures.
