摘要: AbstractTo explain the peak in load-displacement diagram observed blanking and related processes, three modes of shear instability are introduced: two geometrical concerned with process microstructure, thermoplastic which is dependent on physical parameters material. Except for materials low density specific heat, quite likely to occur, load corresponds activation owing combined effects microstructure. It proposed that fracture preceded by instability.
