**v6.04.130** SSNV130 —Straight cracked elasto-plasticity pipe subjected to bending
====================================================================================

**Summary:**

The problem under consideration is a cracked right tube with a semi-elliptical circumferential defect in the inner skin. The straight tube is subjected to a bending moment. This test makes it possible to calculate the local energy restoration rate at the bottom of the crack by the G-theta method (command CALC_G). The local energy return rate is calculated according to interpolation LINEAIRE. The integration rings are defined by the data of the number of layers (NB_COUCHE_INF and NB_COUCHE_SUP).

The value of G at the bottom of a crack is compared to a score used for the validation of simplified methods in fracture mechanics.
