LS-DYNA: 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.

LS-DYNA for arbitrarily nonlinear structural dynamics

Simulation of very large deformations and the most complex contact scenarios

LS-DYNA solves tasks with complex nonlinearities and avoids convergence issues. For example, short-duration dynamic applications, such as drop, impact and crash simulations, can be performed, e.g. nonlinear processes with large deformations, stability problems and complex contact problems.
