Abstract:
Fine-blanking is an advanced metal forming process derived from conventional blanking process.Since it is a large,localized plastic deformation process,and dramatic material flow occurs in the shearing band close to the edge of punch and die,still some difficulties exist during the process simulation.In view of ductile damage,ductile fracture criterion,simulation of fracture occurrence and propagation,the developments of some corresponding technologies were reviewed in the numerical simulation of fine-blanking process.
