 Stamping-Crash Coupled Analysis Example2: Mitsubishi Motors Corporation / Vehicle Crash analysis with work hardeningMitsubishi 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. The more detail is described in their technical review.
