Forming Limit Stress Diagram Prediction of Pure Titanium Sheet Based on GTN Model

In this paper, the initial values of damage parameters in the Gurson–Tvergaard–Needleman (GTN) model are determined by a microscopic test combined with empirical formulas, and the final accurate values are determined by finite element reverse calibration. The original void volume fraction (f(0)), th...
