**v7.22.137** FORMA41 - Practical work from the "Civil Engineering" training: taking into account withdrawals in the study of a 3-point flexure beam
====

**Summary:**

This test :math:`\mathrm{3D}` illustrates on a simple case the questions relating to the modeling of shrinkages in concrete; it highlights the effect of drying and temperature on the distribution of stresses.

It is a reinforced concrete beam subjected to 3-point bending to which thermal and drying stress is added.

The objective of the test is to show the possibilities of modeling withdrawals by chaining thermal THER_NON_LINE and mechanical MECA_STATIQUE calculations.

Modeling A corresponds to the calculation of flexure in elasticity. It is used as a comparison for the other models.

Modeling B corresponds to the calculation taking into account desiccation shrinkage, endogenous shrinkage and thermal expansion.
