Transient simulation of impact, drop and crash tests

LS-DYNA is suitable for simulating nonlinear processes with large deformations, stability problems and highly complex contact scenarios.

Simulation of short-duration dynamic effects and highly nonlinear problems

Using the explicit time integration method within LS-DYNA, very fast and highly dynamic problems can be effectively simulated. LS-DYNA is also suitable for quasi static problems involving high nonlinearities wherein implicit time integration method cannot be used because of convergence issues.

What our customers say

Jochen Armbruster
Head of CA Tools & Prototyping, Hansgrohe Deutschland

Integrating LS-DYNA into Workbench has increased the benefits for us, as we can now handle all tasks involving structural mechanics and CFD in one application interface.

Andreas Junk
Computational engineer

By explicitly simulating a drop test, we were able to easily and affordably predict a thermal imaging camera’s deformation behavior.
