Vectorial rapresentaton of State Variable in ABAQUS
Forums
Choose a channel featured in the header of iMechanica
Hello,
I qould like to represent a State Variable of my Abaqus UMAT with a vector field. Is it possible to do that? How do I proceed?
Thank you in advance!

Hi all,
I am new to ABAQUS. I need to write a subroutine for thermal gradient in USDFLD. But I am not able to do that. Can anyone help me to do that.
Thanks in advance
Theoretical study of magneto-rheological elastomers
I post the links to some of our recently published papers on magneto-elasticity. These are iron-filled elastomers whose mechanical properties can be influenced by the application of a magnetic field. A continuum theory that accounts for magneto-mechanical coupling as well as rate-dependent energy dissipating deformations is presented.
I also attach post-print versions of these articles here. Hopefully, they can be useful for some people working in this field.

Abstract
determination of stiffness matrix of transversely isotropic material
Dear all, I am an applied mathematician and I have been stucked by the this general question for a while, i.e., to determine the stiffness matrix of transversely isotropic material from known strain and stress tensors. The definition of transversely isotropic tells us that the stiffness matrix can be defined by 5 constants, see attached figure. C44 is easy to determine, so we can focus on the remaining 4 constants. I attempted to establish 4 linear equations for these 4 constants with the known strain and stress components.
