Programming Initial Conditions (stress) with Python

[RGX124]

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.

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.

May be this help..

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.

You can use the Keyword editor to insert *initial conditions, from the Python script.

This is supported by the Abaqus Scripting Interface (Python-based).

See the KeywordBlock object in Abaqus Scripting Reference Manual.

Best.
