description LS-DYNA Overview

LS-DYNA is the gold standard for explicit dynamics and high-speed impact simulations. It is widely used in automotive crash testing, ballistic analysis, and explosion modeling. Its ability to handle extreme deformations and complex material interactions makes it indispensable for safety engineering.

help LS-DYNA FAQ

What is LS-DYNA mainly used for?

LS-DYNA is widely used for explicit dynamics simulations such as automotive crash, impact, blast, and forming problems. It is especially strong when materials undergo large deformation.

Who develops LS-DYNA now?

LS-DYNA was originally developed by Livermore Software Technology Corporation, often called LSTC. Ansys acquired LSTC in 2019, so LS-DYNA is now part of the Ansys simulation portfolio.

Why do automotive companies use LS-DYNA for crash testing?

Crash events happen over milliseconds and involve contact, buckling, fracture, airbags, seatbelts, and complex materials. LS-DYNA's explicit solver is well suited to those high-speed nonlinear events.

How is LS-DYNA different from a normal static FEA tool?

A static FEA tool is usually aimed at slowly applied loads and equilibrium states. LS-DYNA focuses on transient events where inertia, contact, and material failure dominate the result.
