Abstract

Cockcroft-Latham fracture criterion was applied to predict the fracture of high strength steels. Marciniak-type biaxial stretching tests of the high strength steels were carried out to measure the material constant of Cockcroft-Latham fracture criterion. Furthermore, in order to improve the simulation accuracy, the local anisotropic parameters depending on the plastic strain were measured by Digital Image Reconstruction system and incorporated into Hill's anisotropic yield condition. To confirm the validity of Cockcroft-Latham fracture criterion, the uniaxial tensile tests were performed. The force-displacement history and fracture happening strokes were predicted with high accuracy.
