This paper is concerned with evaluation of various ductile fracture criteria in a general three dimensional (3D) stress state of stress triaxiality, the Lode parameter and the equivalent plastic strain to fracture. Evaluation is carried out by comparing fracture loci constructed by fracture criteria to experimental results of Al2024-T351. Comparison demonstrates that the Modified Mohr-Coulomb criterion and a newly proposed criterion provide sufficient predictability of fracture strain. Moreover, evaluation is emphasized on the predicted cut-off value for stress triaxiality. Evaluation suggests that the Cockcroft-Latham, Brozzo, Oh, Ko-Huh and the new criteria coupled a reasonable cut-off value for ductile materials.
