Forming Limit Stress Diagram Prediction of Pure Titanium Sheet Based on GTN Model. [PDF]
Materials (Basel), 2019 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.

Determination of the Constants of GTN Damage Model Using Experiment, Polynomial Regression and Kriging Methods [PDF]
Applied Sciences, 2017 Damage models, particularly the Gurson–Tvergaard–Needleman (GTN) model, are widely used in numerical simulation of material deformations. Each damage model has some constants which must be identified for each material.
