1目的1Purpose此测试规范描述了如何执行板材弯曲测试和确定弯曲角度。弯曲测试用于得出金属材料在弯曲变形为主导的加工过程(例如折弯操作)中,或者在冲击载荷作用下,有关成型过程和失效敏感性的一些结论。This test specification describes how to perform the plate bending test and how to determine the bending angle. The tests are intended to draw conclusions about the forming behavior and the susceptibility to failure of metallic materials during forming processes with dominant bending portions (e.g. hemming operations) or during crash loads.2适用范围2Scope本试验规范适用于改良对金属材料样品进行的弯曲试验,例如高强度
