Figure 1.1-1: **G** geometry **of the tube**


**v6.04.131** SSNV131 —Straight cracked elasto-plasticity pipe under combined loading
=======================================================================================

**Summary:**

The problem under consideration is a cracked straight tube with a semi-elliptical longitudinal defect in the inner skin. The straight pipe is subjected to a loading of combined pressure and 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 restoration rate is calculated according to the 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.
