Application of an Advanced GTN Model [PDF]
The present contribution consists of implementing an advanced GTN damage model as a "User Material subroutine" in the Abaqus FE code. This damage model is based on specific nucleation and growth laws.This model is applied to the prediction of the damage ...

Experimental Investigation of GTN model parameters of 6061 Al alloy
This research experimentally determines the Gurson-Tvergaard-Needleman (GTN) model damage mechanics parameters for 6061 Al alloys. Five different heat treatment conditions including T4 (natural aging) and T6 (peak strength) conditions of 6061 Al alloy ...

Formability prediction using bifurcation criteria and GTN damage model [PDF]
In this paper, four plastic instability criteria, which are based on the bifurcation theory, are coupled with the GTN damage model for the prediction of diffuse and localized necking.

Forming limit diagram prediction of 6061 aluminum by GTN damage model [PDF]
Forming limit diagram (FLD) is one of the formability criteria which is a plot of major strain versus minor strain. In the present study, Gurson-Tvergaard-Needleman (GTN) model is used for FLD prediction of aluminum alloy 6061.

Determination of the Constants of GTN Damage Model Using Experiment, Polynomial Regression and Kriging Methods [PDF]
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.

Finite element simulation of rotary blanking based on a modified GTN damage model [PDF]
Based on the GTN model,a modified GTN model applicable to compressive stress conditions was established by considering the effect of microvoid shear deformation on the loss of load-carrying capacity. The elastic-plastic constitutive model with the damage
