摘要

The basic theory of stress triaxiality and Lode angle was discussed. A series of tests including up- setting tests, shear tests and tensile tests on mild steel providing clues to fracture ductility for a wide range of stress triaxiality were carried out. There was a sharp decrease in low stress triaxiality region, which was studied and explained based on stress triaxiality and Lode angle. New fracture criterion parameters were given through genetic algorithm, and the accuracy of parameters was identified by comparing different fracture criterions with experimental data.
