GTN damage model

In this product, the modified GTN damage Abaqus VUMAT subroutine material model proposed by Gatea et al. (2017) was developed. In this material model, in addition to the original GTN model, the effects of plastic anisotropy and shear loading conditions have been added to increase the accuracy of solving the original GTN damage model. Also, the results have been verified and validated (V&V) with valid papers, and at the end, the extended damage model is compared with the Abaqus built-in GTN model known as the porous metal plasticity model.
