.. _V6.04.115: **v6.04.115** SSNV115 - Corrugated sheet metal in non-linear behavior ================================================================== **Summary:** This problem validates the law of elasto-plastic behavior with the Von Misès criterion for isotropic linear work hardening for models of plates [:ref:`R3.07.03 `] and solid shells [:ref:`R3.07.04 `] where membrane and flexure effects are also important. The geometry of the model respects 3 constraints: * the thickness is small to respect the hypothesis of thin shells, * the problem must be in plane deformation according to :math:`\mathrm{Oz}`, * the curvature according to :math:`\mathrm{Oy}` is chosen so that the "flexure" and the "membrane" are both significant. There is no analytical solution. Modeling A (2D D_ PLAN) is used as a reference. The test has no physical significance and the values of the displacements obtained are very significant compared to the dimensions of the initial structure. This test is therefore rather a test of non-regression and inter-model comparison. The results (while moving) differ by 2 to 3% between the plate models and the 2D reference. This difference is reduced to 0.5% between the solid shell models and the 2D reference. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Bibliographie Mod_lisation_A Mod_lisation_B Mod_lisation_C Mod_lisation_D Mod_lisation_E Synth_se_des_r_sultats
