Material Model

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

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

Hi all,        I want to capture strain-rate behaviour of materials but unfortunately abaqus does not have Cowper-Symonds which is a widely used (simple) model. However johnson-cook is to complicate for me as not much details are available in literature as i am modeling bio-materials. Is there any good substitute for Cowper-Symonds models in abaqus. Thanks.

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
