B modeling
==============

Characteristics of modeling
-----------------------------------

Modeling DKT. Unit thickness (to find the same reference solutions as the C_ PLAN case). Linear kinematic work hardening behavior is modelled in four ways:


* or using behavior VMIS_CINE_LINE, by taking:

D_ SIGM_EPSI = :math:`E.C(T)/(E+C(T))` with :math:`C(T)=(1000+2990.T)`


* or using behavior VMIS_ECMI_LINE, by taking:

D_ SIGM_EPSI = :math:`E.C(T)/(E+C(T))` and the Prager constant :math:`\mathit{PRAG}=2/3C(T)`


* or using behavior VMIS_CIN1_CHAB, keeping only linear kinematic work hardening: All you have to do is then take: :math:`{R}_{0}={R}_{I}=\mathit{SIGY}`, :math:`b=0`, :math:`{C}_{I}=C(T)`, :math:`{G}_{0}=0`


* or using behavior VMIS_CIN2_CHAB, by choosing the parameters in such a way that the two kinematic variables are identical: All you have to do is then take:

:math:`{R}_{0}={R}_{I}=\mathit{SIGY}`, :math:`b=0`, :math:`C{1}_{I}=C{2}_{I}=C(T)/2`, :math:`G{1}_{0}=G{2}_{0}=0`

Temporal discretization: 1 time step between :math:`t=0s` and :math:`t=1s` and 40 time steps between :math:`t=1s` and :math:`t=2s`.


Characteristics of the mesh
----------------------------

The mesh consists of one QUAD4 mesh and two TRIA3 mesh
