v3.01.106 SSLL106 - Straight pipe

Summary:

This test allows a simple verification of straight pipe elements in the mechanics of linear static structures. The model is linear.

For each model, 6 types of loading are applied at the end: a pull, 2 shear forces, 2 bending moments and a twist. In addition, internal pressure, distributed linear force, and thermal expansion are applied.

The values tested are the displacements, the nodal forces, and the stresses and deformations at the Gauss points. The reference solution is analytical (RDM).

• Two models (A and B) allow you to test the TUYAU element with 3 Fourier modes (modeling TUYAU_3M): modeling A uses MECA_STATIQUE, modeling B uses STAT_NON_LINE (elastic behavior).

• Two models (C and D) allow you to test element TUYAU with 6 Fourier modes (modeling TUYAU_6M).

• Two models (E and F) allow you to test element TUYAU with 3 Fourier modes and 4 nodes (modeling TUYAU_3M).
