Dear Reader,
I recently took over as the ESIS blog editor. Being the second in this baton relay, I will do my best to live up to the good reader expectations that have been established by my precursor, who is also one of the instigators of the blog, Wolfgang Brocks.
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
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.
Research paper.

What are case studies?
Case Studies in Engineering are a series of open access journals, which publish practical outcome of research and indusrty projects in a variety of Engineering disciplines, including: Construction Materials, Fire Safety, Structural Engineering, Engineering Failure Analysis, Mechanical Systems and Signal Processing, Nondestructive Testing Evaluation and Thermal Engineering.

Abstract
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.
