The main purpose of the Bend testing is to determine the ductility, bend strength, fracture strength and resistance to fracture of the specimen i.e the characteristics used to determine whether a material will fail under pressure and are especially important in any construction process involving ductile materials
The bend test is a simple and inexpensive qualitative test that can be used to evaluate both the ductility and soundness of a material. It is often used as a quality control test for butt-welded joints, having the advantage of simplicity of both test piece and equipment.
