Abstract
Finite element modeling based on both 3-D shape measurement and experimental stress-strain relationship was applied to the FEM simulation for estimating the crashworthiness of automobile parts. Compared with the result dynamic crash test using hat-square-column type specimen made of 300 - 590MPa grade steels, the accuracy of the FEM simulation was evaluated for various modeling methods. It was revealed that the modeling of corner radius, bulging of specimen wall and strain rate sensitivity of materials played important roles in predicting the actual dynamic deformation process and the force-stroke relationship.
