v7.22.122 HSNV122 - Thermoplasticity and metallurgy in large deformations under simple traction

Summary:

We treat the determination of the mechanical evolution of a cylindrical bar subjected to known and uniform thermal and metallurgical changes (the metallurgical transformation is of the bainitic type) and to mechanical tensile loading.

The behavioral relationship is a model of plasticity in large deformations (command STAT_NON_LINE, keyword DEFORMATION: “SIMO_MIEHE”) with linear isotropic work hardening and transformation plasticity.

The elastic limit and the slope of the tensile curve depend on temperature and metallurgical composition. The expansion coefficient depends on the metallurgical composition.

The bar is modelled by axisymmetric elements.

The mechanical load applied is a follower pressure.

This test case is identical to test case HSNV101 (modeling B, [V7.22.101]) in the sense that it is the same material, the same load and the same thermal and metallurgical evolutions but in a version with large deformations.
