v6.04.170 SSNV170 - Elasto-viscoplastic cube under simple traction (constant deformation rate)

Summary:

This elasto-viscoplasticity test case makes it possible to implement an axial creep test. The first two models (non-linear) simulate a simple tensile test with a constant imposed deformation rate. C modeling is based on B modeling with different materials and charges to activate the pseudo-discharge of VISC_TAHERI. In the three models, the traction is performed on a cube modeled in 3D with a HEXA8 mesh.

• Modeling A

  • Use of Lemaître’s nonlinear viscoplasticity behavior relationship [R5.03.08].

• B modeling:

  • Use of Taheri’s cyclic elasto-plasticity behavior relationship [R5.03.05].

• C modeling:

  • Use of Taheri’s cyclic elasto-plasticity behavior relationship with activation of pseudo-discharge.
