摘要
In order to be able to reproduce complex phenomena that are actually occurring by a simple method that takes into account the deformation history of both press forming and impact, and to perform high-precision impact performance evaluation tests with little variation in results, , in a test method for evaluating the impact resistance performance of a metal plate for an automobile body, first bending a flat test piece made of a metal plate to be tested into a V-shape by a press working device, and then by a bending test device , The primary bending-formed test piece is subjected to secondary bending deformation in a direction intersecting the primary bending direction, and the bending load and bending stroke of the test piece during the secondary bending deformation are recorded and evaluated.
