There are 4 different types of bend tests that is commonly used in most industries. A guided bend test is where the material is placed horizontally in between 2 supports and then the force is applied right in the middle, ideally bending it into a U shape. A semi-guided bend test is done by bending the material to a specific angle or radius. A free bend test is where the ends of the material are pushed towards each other, but no force is applied to the middle. A common fracture toughness test uses a material that is pre-fractured, and then the bending force is applied at the opposite face from the fracture. Any of these tests can be used strategically to obtain specific data about a material’s bending characteristics.
