my problem is simulation of axisymmetric cold extrusion die. the die is conical, i have to determine die pressure, ram force and temprature in billet as well in die, plz see attached file and see simulation figure, my problem is same as in file,i have facing interaction problem in abaqus while solving this problem. plz help me

Salam and Hi!
My 1st paper was published in Jurnal Mekanikal UTM in June 2008. Please comment and critic on my research works! The paper is here, PREDICTION OF PROGRESSIVE FAILURE IN WOVEN GLASS/EPOXY COMPOSITE LAMINATED PANELS.
Thanks!
Hi,
The data obtained from tensile test is not reliable after the point of maximum load as neck initiates and triaxial state of stress develops.There is lot of literature in this regard, Can anyone suggest a good method to obtain the exact load disp curve after necking.

A new paper titled "Enabling Ultrahigh Plastic Flow and Work Hardening in Twinned Gold Nanowires " from Dr. Sansoz's group just came out on the latest issue of NanoLetters. Attached below is the abstract and the full paper can be found at: http://pubs.acs.org/doi/abs/10.1021/nl803553b. We welcome any comment about this paper as well as our research.
Hello To one and All,
I am currently working on my Master's thesis in Computational
Mechanics and as the Title suggests, I am working on using phase field
theories to model fracture mechanics. The whole idea /concept of phase
field modelling in itself has been a very complex topic for me, as it
originates in superconductivity theories of which I have but a
superficial understanding. I am ok with fracture mechanics terminology
as I have worked on it before.
Hi to the community !
I would like to ask if anyone have some experience with stochastic finite elements in an industrial context ?
Would you know some software (free or commercial) package for stochastic finite elements ?
Why do I have the feeling that sfem methods which look to be very promising aren't used much in practice ? Am I wrong when I say that ?
Thank you very much for any help about that !

Hi, I am a reserach fellow of mechanical engineering in Italy. I need to implement the elasto-viscoplastic model of Chaboche in a user subroutine in ANSYS accounting also for the plastic strain memorization and for the static and dynamic recovery. In a next step I sould also need to incorporate the damage variable of this model.
