v6.02.503 SSNL503 - Elasto-plastic ruin of a thin bent pipe

Summary:

This test consists in calculating the elasto-plastic ruin of a thin bent pipe subjected to bending in its plane and to internal pressure with a shape effect. It makes it possible to validate finite element modeling TUYAU (SEG3 and SEG4) and TUYAU_6M () and (SEG3) in the quasi-static domain in non-linear material.

The results obtained are compared to a numerical reference solution obtained with the calculation code ABAQUS.
