v6.04.266 SSNV266 — Validation of the GTN viscoplastic gradient damage law with bar simulations

Summary:

This test case, very strongly inspired by SSNV256, makes it possible to validate the algorithm for integrating the Gurson—Tvergaard—Needleman damage law (\(\mathit{GTN}\)) in gradient viscoplasticity with sub-integrated standard finite elements. A bar containing 10 finite elements is modelled.
