Determination of the Constants of GTN Damage Model Using Experiment, Polynomial Regression and Kriging Methods
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. The direct identification methods are costly and time consuming. In the current w...
