Fracture forming limit curve prediction by ductile fracture models
Procedia Structural IntegrityThe fracture forming limit curve is an essential tool giving information about fracture initiation in metal forming applications. In order to obtain a fracture-forming limit curve, the Nakajima test should be carried out. However, these tests are costly and time-consuming processes.
