Programming Initial Conditions (stress) with Python
Programming Initial Conditions (stress) with Python
(OP)
Hi,
I would like to integrate an initial stress state in an Abaqus model via the Python subroutine.
I know that Initial stress is not supported in Abaqus/CAE. (see below). However the input file supports it.
Is it possible to find a way to program it via the Python interpreter?
Thanks for your help.

R
Defining initial stresses for rebars
Initial values of stress can also be defined for rebars within elements (see "Defining rebar as an element property," Section 2.2.4).
Input File Usage:
*INITIAL CONDITIONS, TYPE=STRESS, REBAR
Abaqus/CAE Usage: Initial stress is not supported in Abaqus/CAE.

mdb.models['Model-1'].KinematicHardening(definition=REBAR, name='rebar-hardening', region=region, field=', distributionType=MAGNITUDE, numBackStress=1, rebarLayerNames=('rebar-layer1', ), equivPlasticStrain=(0.00035, ), backStress=((0.2, ), ))

This is only available in v6.8 though.

This is supported by the Abaqus Scripting Interface (Python-based).
See the KeywordBlock object in Abaqus Scripting Reference Manual.
Best.
