Calculating material jacobian matrix for ABAQUS UMAT subroutine

Hello everyone,

I found that there is no comprehensive topic about how to calculate material jacobian matrix for UMAT while it's one of the most complicated and important parts of writing a subroutine and a lot of the researchers deal with it.

I think it would be great if experts share their sources and experiences here for all. I personally, try to provide the basics and essential materials as well.

Here is an essential available PDF on Imechanica:

Transformation Matrix

Hello,

The attached file describes the development of the transformation matrix of a beam element:

postdoc position in computational mechanics

A postdoc position is available in the Computational Mechanics Lab at the University of Texas at Dallas. The research will focus on high-performance computing application in the general field of computational mechanics. The potential candidate shall have a Ph.D. degree in mechanics, mechanical engineering and related areas with emphasis on computation and simulation and integration with experiments. The project will involve extensive programming on HPC platforms.

what is the reason for Large element deformation?

Hi my Friends,

I am doing abaqus run for a copper specimen under hydrostatic pressure. The magnetude of pressure is in order of several Giga Pascals. In my material definition, I have defined stress-strain flow up to strain of 0.4. But as you can see in attached photo, some elements show very large deformation (considerably larger than 0.4). Knowing that I have not defined stress strain behaviour for srain greater than 0.4, how this can be occure? Unfortunately, niether adaptive meshing nor element deletation were not eliminate this issue!!

Best Thanks

Finite Element Model of the Knee

Hello Everyone,

I recently started to do a project on a FE knee model. Right now, the only available software for me is SolidWorks which was originally purchased for CAD modelling. I was wondering if anyone knows whether SolidWorks FE feature is "good enough" for analyzing a knee model (and for other tissues just in case), or you recommend me to push my supervisor to purchase a license of a "Real" FE software such as ABAQUS. If you have any experience of FE modelling of tissues,bone,etc. I would appreciate if you help me out.

Development of a Biofidelic Human Head Model from MRI data

Traumatic brain injuries from head impact are a major issue across areas such as defence, automotive and sports, and can be costly to research using experimental testing. These injuries can be explored, though, through 3D models created from scan data and computer simulations.
