Hi,
I am trying to develop a finite element code to capture the residual stresses during the cooling of a viscoelastic body.
Can anyone suggest references or papers that address the finite element formulation of a thermoviscoelastic problem? I have found a couple of papers, but they do not seem to directly apply to what I want.
Thanks,

For bifurcation buckling, we have the following eigenvalue problem:
(K+Lambda Ksigma)delta d= 0

I guess it is about time some one from the Cornell Fracture Group got on this site to try help answer questions related to the CFG software or other fracture mechanics related questions. We do try to answer questions sent to us via email, but sometimes a forum like this would be best and we do appreciate other users input, feedback, and answers.

Obama spoke at the National Academy of Sciences on Apr. 27, 2009, in which he states his commitment to doubling of science funding and stem education. From his speech,
"At such a difficult moment, there are those who say we cannot afford to invest in science, that support for research is somehow a luxury at moments defined by necessities. I fundamentally disagree. Science is more essential for our prosperity, our security, our health, our environment and our quality of life than it has ever been before."
hi...i am doing drilling simulation on abaqus....
it consist of two parts...a tool and a blank....
now when i am running analysis...tool touches the blank and goes back.
i checked material data...density,elasticity...and i used surface to surface interaction with penalty as interaction property....
can any one tell me ...how to perform this....
Hi all
I am a new ABAQUS VUMAT user. Recently, I try to substitute the explicit intergation method in VUMAT by back EULER intergation method. But the calculated equivalent stress is nonuniform for simple compression test. Would anyone pls help me find the reasons? Many thanks. Attached pls find the VUMAT subroutine and INP file.
