Separating brittle materials e.g. casting risers, involves applying compression stress perpendicular to surface of brittle material, minimizing tensile stress applied at 45 degree angle to material during shearing process

摘要

The method involves applying compression stress perpendicular to the surface of a brittle material to be separated, minimizing tensile stress applied at 45 degree angle to the material during shearing process. The material is cut as the applied stress is larger than the material shearing strength.
