.. _V6.04.250: **v6.04.250** SSNV250 — Elementary validation of the damage law GTN in the case a xisymmetric ======================================================================================================== **Summary:** This test case makes it possible to validate the algorithm for integrating the local and gradient Gurson—Tvergaard—Needleman damage law (:math:`\mathit{GTN}`) with underintegrated or mixed standard finite elements in large deformations. A volume element is modelled in simple traction. The various models treated are: * **A** Modeling** (:math:`2D`): AXIS_SI. * **Modeling** **B** (:math:`\mathrm{2D}`): AXIS_GRAD_VARI. * **Modeling** **C** (:math:`\mathrm{2D}`): AXIS_GRAD_INCO. * **Modeling** **D** (:math:`3D`): 3D_SI. * **Modeling** **E** (:math:`\mathrm{3D}`): 3D_ GRAD_VARI. * **Modeling** **F** (:math:`\mathrm{3D}`): 3D_ GRAD_INCO. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Mod_lisation_B Mod_lisation_C Mod_lisation_D Mod_lisation_E Mod_lisation_F Synth_se_des_r_sultats
