Vehicle Crash analysis with work hardening
Mitsubishi Motors Corporation(MMC) uses LS-DYNA for crash analysis, which are one of the biggest issue that LS-DYNA is adopted. MMC tries to get higher accuracy to expect the performance of the vehicle body.
To get to know high accuracy of the material property is one of their try. Now, they have chose HYCRASH to calculate residual strain and thickness distribution, which is conducted before the crash analysis. They could get higher accuracy using HYCRASH with combination of LS-DYNA.

Achievement
HYCRASH uses one-step solution to calculate the residual strain and changes in thickness during forming, to deal with work hardening. This means that additional data for performing the forming simulation are not required and that the calculation time is dramatically reduced. Now, with HYCRASH support, users can perform a highly accurate simulation with work hardening.
