Fracture is generally defined as material separation. A brittle fracture permits no plastic deformation prior to fracture. It is the separation of solid accompanied by little or no macroscopic and /or microscopic plastic deformation. A ductile fracture is capable of being plastically deformed before fracturing. In the macroscale point of view it indicates plastic deformation associated with fracture (Implies high energy absorption). In the microscale point of view it describes plastic deformation associated with fracture ,typically by microvoid coalescence.
This will also be useful for students preparing for Gate exam and PSU's exam.
