Our group at North Carolina State University is hiring PhD students and Post-doctoral Associates in the areas of multiscale modeling, computational mechanics, fracture, and plasticity.
Interested parties should email zikry [at] ncsu.edu, and send a cv with a few representative publications.

sir, need help regarding modeling of pyro ejection load where full structure is in airborne..
please help ...

Hi
I use FEMFAT to predict the fatigue life of welded structures. FEMFAT can take the effect of plastic strain on fatigue life but the stress results should imported from ABAQUS or LS-DYNA. Since I've simulated the welding process in ANSYS, I want to know that is there any way to convert ANSYS results(file.RST) to ABAQUS(file.ODB) or LS-DYNA results(file.d3plot).
The Department of
Industrial Engineering at the University of Pittsburgh anticipates an opening
for a postdoctoral associate starting September 2012. The position’s primary
area of research will focus on mechanics of the microforming processes and
characterizing the thermomechanics of deformation at small length-scales. The
initial appointment is for one year with potential to extend, subject to the
availability of funds. A strong background in solid mechanics with an expertise
in computational crystal plasticity and finite element modeling of
Dear all,
These days I am doing some research on vibration analysis with uncertain properties. In traditional, Monte Carlo Simulation is used to do this simulation. But the drawback is time-consuming for the determinstic analysis.
For this, how to solve this problem? Please help me on it. Please give me some suggestion on it.
Thank you for your concern.
Hi
i am interested to study the morphology of polymeric membranes in non linear regime. I am in search of what actually a 'non linear behavior in a material represents'. Mathematically there are certain equations governing the non linear behavior. But my concern is how material behaves in non linear regime (under moderate to high stress). And what molecular and microstructural features contributes to the non linear behavior?. Can any one post me to under stand the micro sructural behavior of polymers in non linear regime. It would be useful help to me.
The interpretation of general return mapping integration algorithm as closest point projection of the trial stress state leads to a lagragian with arguments as the state of the system. In the hardening regime, this lagragian is convex and newton's method guarantee uniqueness and convergence (Simo and Hughes). I am interested in the case when the lagragian is no longer definetively convex as could be the case in softening regime. Can anybody suggest me numerical techniques for this case?

I would like to seek comments on : Room temperature stress relaxation and governing mechanisms that contribute to the plasticity that occurs during this process. As, most of the available work on relaxation is done at elevated temperatures.

I have also attach papers by Prof Hart and Prof Krempl that did throw some light on this particular subject.
hi everybody,
I'm a fresh man in Abaqus. Recently, I find that the command 'abaqus cae script=job.py' works very well, however, the command 'abaqus cae noGUI=job.py' doesn't work. But the the 'job.py' is exactly the same! By the way, the problem shown by abaqus is located in the output area, fieldfieldoutput and historyouput.
Does anyone know the difference between them?
Thank you in advance!

Hi friends
I´m modeling Flexible Pavements in Abaqus and I need to model Cyclic load...haow can I do this???
can anyone help me???
Thanks
PD: sorry by my English
