.. _V6.04.144: **v6.04.144** SSNV144 - Elbow flexed during large movements ================================================================ **Summary:** This test validates the modeling of shell flexure phenomena in large displacements in the elastic or elastoplastic domain: a pipe elbow, extended by straight pipes, is subjected to bending in its plane. The pipe is thick (of dimensions similar to the bends of the primary circuits). The reference solution is numerical: it is obtained with *Code_Aster* using a :math:`\mathrm{3D}` elbow mesh. The modeling is carried out with COQUE_3D elements in large displacements or in elastoplasticity. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Synth_se_des_r_sultats
