Ansys workbench
hi.
i want to know the difference between ansys and ansys workbench,
what is the difference between them.. which give good result.
please let me know.
thanking you

Crack-tip field
These notes were initially written when I taught fracture mechanics in spring 2010. The title of the notes was then "stress intensity factor". In revising the notes for the class in 2014, I have changed the title of the notes to "crack-tip field".
You can access all notes for the course on fracture mechanics.
PostDoc position, Karlsruhe (Germany): Mechanics of Granular Materials in Fusion Technology
A research position is now opening in the field of Computational Mechanics of granular materials, in Karlsruhe Institute of Technology (KIT), Germany. This position should start between May and September 2010, and is a full-time fixed-term PostDoc position for 2 years (TVL E13).
FEMhub: Scientific computing for the rest of us
I came across a wonderful site a couple of weeks ago. nb.femhub.com
FEMhub is still at its beginning stage, but it can already do lots of interesting stuff. For someone like me who teaches numerical/computer methods in engineering at a developing country where computing is costly, tools like FEMhub are very much welcome.
More about FEMhub on my website. Try out the example worksheets and I think you'll be pleasantly surprised.
Writing User Subroutines with ABAQUS
Dear All,
I think that many students are looking for some tutorials about writing a UMAT in ABAQUS.
You can find a comprehensive tutorial for elastic problems.
This file contains:
• Motivation
• Steps Required in Writing a UMAT or VUMAT
• UMAT Interface
• Examples
Example 1: UMAT for Isotropic Isothermal Elasticity
Example 2: UMAT for Non-Isothermal Elasticity
Example 3: UMAT for Neo-Hookean Hyperelasticity
Postdoctoral Research Associate at University of Sydney
A Postdoctoral Research Associate position is available in the School of Civil Engineering at the University of Sydney, Australia. The project aims to understand the effects of solid solute, grain size and intermetallic structure on the strength of Mg alloys through modelling and simulation. The project is funded by the Australian Research Council (ARC) Centre of Excellence (CoE) for Design in Light Metals.
Stretching and Spin Tensors Relations
Can someone help me to understand this please:
The stretching tensor (D) is the symmetric part of the velocity gradient (L), and if I derive D from L with using the polar decomposition of the deformation gradient (F=RU) I get the relation:
D=0.5 R (Udot Uinv + Uinv Udot) R' ----(Eq.1) where Udot is the time derivative of U, Uinv is the inverse of U, and the prime indicates the tranpose of the matrix.

Problem with Abaqus subroutine first increment
Hi everybody,
I´m working with umeshmotion subroutine, and Ihave one question.
Once I have submited the job and the subroutine, I can check that the nodes doesn´t move on the first increment in the subroutine´s step (the movement starts on the second increment), but in the .msg file I can see that the calculations has been made in the first increment.
Does anybody knows the reason?
Thanks in advance.
