Hello!
I was wondering if anyone may suggest me what is the best way to calculate in Abaqus average stress and strain over a set of elements (2d, continuum) without using user subroutine?
I can obtain stress 'S' and integration point volume 'IVOL' from odb file using python script. However, it seems that volume of integration point 'IVOL' variable in given the reference configuration and i can't use it to average Cauchy stress without transforming the stress to reference configuration, or transforming volume to current configuration (but deformation gradient and jacobian are not available in the output). For example, the script given here( seems to be valid only for small deformations, as it doesn't account for the volume changes.
Also what is the meaning of abaqus IVOL variable in 2d plane stress analysis? Is it volume which is preserved for incompressible material or it is area, which is not preserved?
Thank you!
