What are the types of fracture?

Under the action of stress, the object or material is separated into two or more pieces, this process is known as Fracture. Within the solid, because of the development of certain displacement discontinuity surfaces fracture occurs.

1. Ductile fracture: It is done because of the large amount of plastic deformation before the parts can fail. The cross-section of the material is reduced after the failure. At the latter part, you can observe the shear lips which means the part is failed. The surface of the part now gives a dull and fibrous appearance
2. Brittle fracture: Unlike Ductile fracture, no plastic deformation takes place before fracture in Brittle fracture. In comparison with the Ductile fracture Brittle fracture usually occurs at high speeds and involves little energy absorption. The characteristics of brittle fracture can be seen with very little plastic deformation and a shiny fracture surface. You can observe the brittle failure starts at a notch or stress concentration and spread with plastic deformation
