Hi,
I am working on short glass fibre reinforced composites.
Is there a material model which can predict the fatigue behaviour of the composite structure at high temperature.
Thank you

it's a basic problem. In LS-DYNA, with explicit or implicit method, one material model is only suitable for some element formulations/types, but not for all element types. There must be many deep reasons and some aspects to be considered.
why element formulation can not independent on material model?
could you tell me some detailed deep reasons or links about this? thanks!
There are a couple of funded PhD positions available at the University of Auckland, New Zealand.
The topics are, roughly,
1) Advanced material models and variability
2) Biomimetic sensing and adhesion.
The deadline for applications is Friday, October 29, 2010. Please send a current CV, a statement of purpose, and transcripts/grades from your undergraduate work (and master's work if you have a master's degree in a related field).
Hi all,
I would like to model the transformation of austenite to bainite and martensite in the simulation software DEFORM 3D.
I am not so much confident with the core metallurgical concepts. I would like to know, if some one has experience in creating a material model using mixture method in DEFORM 3D.
Would like to hear from you.
With Best Regards

I have noticed that a lot of people are using UMAT and VUMAT material model
subroutines for their researches. However, most of these subroutines do not
find their way to free code market and remain in the hands of the developers.
Therefore, a lot of wheel re-inventing has to be done by other people. Since
development and testing of a material subroutine takes a damn long time, I
think it is a good idea if each of us can share the subroutines she has
developed with the others. I know that a couple of subroutines are publicly
