**v6.01.112** SSNA112 — Axisymmetric pull-out test for the study of the steel-concrete bond: law JOINT_BA
==============================================================================================================

**Summary:**

In this mechanical test case, we modelled the pull-out test carried out by La Borderie & Pijaudier-Cabot [:ref:`bib1 <bib1>`], the aim of which was to study the influence of the stress state in the matrix on the mechanical properties of the interface. The geometric data and the material characteristics are taken from their report, and the numerical results will be compared with the experimental results.

For axisymmetric modeling, elements QUAD4 are used for concrete and steel, in combination with joint elements for the interface (see doc. [R3.06.09]). Concrete and steel are considered elastic in order to test only the nonlinearity of the law of behavior of the steel-concrete bond, JOINT_BA (see document [:ref:`R7.01.21 <R7.01.21>`]). A monotonic calculation is carried out with movements imposed at the end of the steel bar.
