There are two main types in the bending tests of metallic materials. One is for metallic materials with good plasticity. The bending test is mainly used to test the ability of the sample to withstand deformation. The other is for brittle or low plastic materials. The bending test mainly measures its bending strength and other mechanical properties. Summarizing and comparing the bending performance test methods of several metallic materials can provide some guidance for the testers to choose the most suitable method when testing the bending performance of different samples.
