2. Benchmark solution

2.1. Benchmark results

As reference results, we will adopt the displacements, the Cauchy stress \(\sigma\) and the cumulative plastic deformation \(p\) obtained with the behavior VMIS_ISOT_TRAC (also validated with DEFORMATION =” SIMO_MIEHE “and” GDEF_LOG “).

We will compare the solutions obtained at time \(t\mathrm{=}\mathrm{2 }s\) (\(\Delta T\mathrm{=}100°C\), traction \(u\))

2.2. Uncertainty about the solution

Very low since it is a question of inter-comparison between two formally identical behaviors. However, the discretization of the law of work-hardening in terms of power leads to uncertainty.
