Get PriceEmail contactThe reason for splitting is that the tensile stress on the splitting plane reaches or exceeds the tensile strength limit of the material. 3. Folding: The material is crushed under the action of bending stress. The crushed material will be broken and crushed when the bending stress of the material reaches the bending strength of the material.
