v6.01.110 SSNA110 - Recalibrating parameters with the VISC_CIN2_CHAB template

Summary:

This nonlinear quasistatic mechanical test makes it possible to validate the readjustment of parameters for model VISC_CIN2_CHAB in \(\mathrm{2D}\) in the case of an axisymmetric specimen (state of stress and homogeneous deformation) subjected to a simple tensile test.

Four traction curves serve as a reference (at different deformation rates). The reference curves are the result of tests on steel \(10\mathrm{CD}9-10\) to \(545°C\).

The 11 viscoplastic parameters of the model are simultaneously identified.

The modeling of the test piece is carried out with an element \(\mathrm{2D}\) (QUA4).
