The level of rigidity of the metal to be made (often sheet, strip, plate, bar, and wire) is measured throughout this process. In addition, it is used to evaluate the strength and hardness of metal (after welding, etc.). The sample is typically bent over a tool with a fixed diameter. Free, guided, semi-guided, and wrap-around bend are the four common types of bends, according to ASTM E290, E190, A370, and various IS, BS, and ISO standards.
The bend test is used to determine the material’s ductility and flexibility. It serves in figuring out the material bending capacity without breakage or failure.
Depending on the material and the test requirements, different bending procedures are used. Three-point bending, four-point bending, and mandrel bending are popular procedures.
Doing bend test of a material, a number of factors are evaluated, including the angle of deflection, the existence of cracks or fractures, and the material’s capacity to recover its former shape.
