Hello,
I am planing to model a viscolestic material in ANSYS and condition is dynamic.
Could anyone please suggest what are the essential things (i mean datas) required for modeling a viscoelastic material?
For example, If I do the DMA test of viscoelastic materials i can have the modulus data at different frequencies. How to use those data in ANSYS to find out the stress-strain curve?
Thnaks for your kind help

Can I draw your attention to a Chair position and Lectureship in Bioengineering at the School of Engineering, Durham University. While the curent Chair position is occupied by an experimentalist, the postitions are open to candidates with interests in computational modelling and I would encourage anyone in that area to take a look.
Further details are available at the Durham jobs website https://jobs.dur.ac.uk/default.asp. Closing dates are 10/07/09 for the Chair and 31/07/09 for the Lectureship.

Hi there,
I am sure a lot of you have been using ABAQUS to define cohesive elements. I have seen a lot of forums here and a lot of them specified the Alfano 2001 paper as a great reference. Here is the title of the paper incase anyone is wondering which paper:
G. Alfano and M.A. Crisfield, Finite element interface models for the delamination analysis of laminated composites: mechanical and computational issues, International Journal for Numerical Methods in Engineering 50 (2001), pp. 1701–1736.
Dear Colleagues,
The next *WCCM 2010* (World Congress in Computational Mechanics)
Conference will be held in Sydney (AUSTRALIA) on July 19 - 23, 2010.
Within this conference, Stephane Bordas and myself are organizing a
minisymposium dedicated to ...
"Novel discretization techniques for moving discontinuities and

HI All,
i am doing my masters and my thesis is about pipeline integrity.In my thesis, we did J-Integral test for our pipes(20'diameter and 5.7 mm thicjness) after getting results ,according to ASTM we should draw 0.2 line to find J0.2 and the value which i got is around 200 kj/m2 but as you know for pipeline materilas the J should be around 120 kj/m2 ,now i wonder to know if there is any other way for calculating j-integral for pipelines? we also run charpy test and again i am wondering to know if there is any way for corrolating chary to JIC ?
thanks,
ali
Hello,everybody.
Is there someone knows:
Where to find the cohesion value(COHE) of metal for the Friction Model of ANSYS contact analysis?

I am modeling irradiated zirconium using ABAQUS
I am looking for a UMAT that has the HCP stucture in it (slip systems....)
Besides I need to incorporate the damage inside my model (UMAT FILE)
and then I will do indentation on my sample to get mechanical properties.
If anyone has ideas or even any UMAT that is related to damage or HCP structure, I would appreciate his help
Thanks
Elias
