v7.22.120 HSNV120 - Hyperelastic traction of a bar under thermal loading

Summary:

This almost static thermomechanical test consists in uniformly heating a parallelepipedic bar, subjecting it to significant traction and finally letting it return to a discharged state. We thus validate the kinematics of large hyperelastic deformations (command STAT_NON_LINE, keyword COMPORTEMENT) for a relationship of nonlinear elastic behavior (ELAS_VMIS_LINE and ELAS_VMIS_TRAC) with thermal loading.

The bar is modelled by a volume element (HEXA20, ModelizationA).

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