v6.04.122 SSNV122 - Hyper-elastic rotation and follower traction of a bar

Summary:

This quasistatic mechanical test consists in rotating a parallelepipedic bar by 90° and in subjecting it to significant traction by means of following forces. We thus validate the kinematics of large hyper-elastic deformations (command STAT_NON_LINE, keyword COMPORTEMENT), and therefore in particular large rotations, for a linear elastic behavior relationship, as well as the consideration of following forces (command STAT_NON_LINE keyword TYPE_CHARGE =” SUIV “).

The bar is modelled by a volume element (HEXA8, ModelizationA).

For its part, modeling B validates follower loads of the function type depending on the initial geometry.

The results obtained by*Code_Aster* do not differ from the theoretical solution.
