Uncoupled fracture model of Q690 high‐strength steel based on stress triaxiality and Lode angle parameter

In this paper, experiments, numerical simulation, and model construction were all investigated in order to advance the popularization of high-u2010strength steel. The ductility of Q690 steel under plane strain is lower than that under axisymmetric tension, according to a three-u2010 dimension fracture study based on u201cstress triaxiality (u201d) u201d, u201cstress fracture strain/u201d, u201c strain strainu201d, u201d, which shows that the ductility of Q690 steel under plane strain is lower than that under axisymmetric tensions.
