6. H modeling#

6.1. Characteristics of modeling#

  • Tested behavior: ImplicitsiMomieheelastoplasticity.mfront and plasticity.mfront.

Von Mises” elasto-plastic law in large deformations using either the Simo and Miehe formulation, comparable to VMIS_ISOT_LINE, with DEFORMATION =” SIMO_MIEHE “

(cf. [R5.03.21]), i.e. DEFORMATION =” GDEF_LOG “(cf. [R5.03.24]).

  • Modeling and data similar to those of test SSNP159A.

6.2. Tested sizes and results#

The reference solution is the one obtained by behavior VMIS_ISOT_LINE and SIMO_MIEHE.
