Abstract

True stress-strain values were obtained from tensile tests of 7075 aluminum, and by performing a finite element simulation analysis. The results revealed that various ductile fracture criteria resulted in different levels of accuracy in the simulation. Moreover, factors affecting ductile fractures, such as stress, strain, and damage value were analyzed. The normalized Cockcroft and Latham ductile fracture criterion used in the finite element analysis simulation resulted in a higher accuracy than that of other ductile fracture criteria. In the future, finite element simulation analyses applying the A7075 fracture criteria could be used for cutting and stamping materials.
