**v3.01.104** SSLL104 - Pre-deformations in a straight beam
===============================================================

**Summary:**

This test validates the consideration of pre-deformations in the elastic calculation of a straight beam. The characteristics of the calculation are:

• static analysis,

• linear behavior,

• line model

Modeling A validates the consideration of pre-deformations entered by value (AFFE_CHAR_MECA/PRE_EPSI) for the elements POU_D_E, POU_D_T, POU_D_TG, POU_D_EM and POU_D_TGM. The solution is analytical.

The B modeling validates the consideration of pre-deformations entered by function (AFFE_CHAR_MECA_F/PRE_EPSI) for the elements POU_D_E, POU_D_T, POU_D_TG, POU_D_EM and POU_D_TGM. The reference solution is a calculation with pre-deformations entered by value. It is specified that this loading is authorized for beam elements only if the value of the function at the two nodes of the same element is the same.

The C modeling validates, for element BARRE, the taking into account of pre-deformations entered by value, by comparison with the element POU_D_E, and the taking into account of pre-deformations entered by function by comparison with a calculation with pre-deformations entered by value.
