The main application of LS-DYNA in metal forming is sheet metal stamping. The incremental approach of LS-DYNA allows the user to simulate multi-stage sheet metal stamping processes with a high degree of accuracy. The multiple core technology implemented, enables even large components with very high accuracy requirements

All the simulations were run in LS-DYNA® and all the analyses adopted the explicit finite element formulation. The energy ratio criterion was adopted to evaluate the acceptability of the simulations: the

With LS-DY­NA, au­to­mo­tive com­pa­nies and their sup­pli­ers can test car de­signs with­out hav­ing to tool or ex­per­i­men­tal­ly test a pro­to­type, thus sav­ing time and ex­pense. Spe­cial­ized au­to­mo­tive fea­tures in­clude: Seat­belts; Slip rings; Pre­ten­sion­ers; Re­trac­tors; Sen­sors; Ac­celerom ...

The basic functionality of tied contacts is the same for both the explicit and implicit mechanical solver of LS-DYNA. By the Implicit Accuracy flag (IACC) of *CONTROL_ACCURACY, a strongly objective formulation for the tied contacts is activated.

Program (ACFPP) has collaborated to develop a new material model in LS-DYNA for metallic materials. The research was directed towards improving the numerical modeling of turbine engine blade-out containment tests
