residual stress distribution in pipe
Hi every body
I study the residual stress derived from a circumferential weld on the end of a pipe and degree of freedom in the other end have been taken
but i have a problem in residual stress distribution along axis of pipe.
its known that the axial stress at the end of constrainted end should be zero or little but mine is in order of 100 MPa while residual stress is 300 MPa.
can anybody give me a hint about whats the source of error
thanks
TeX-based equation image generator
If you would like to include LaTeX equations in a presentation (Powerpoint, Keynote, or others), and have not found a good solution so far, then you might wan't to consider TeXclip. It is on the web (no installation needed) and high-quality images of the TeX equations can be incorporated into a presentation rather seamlessly. I have been using TeXPoint so far, but do like the simple usage and the quality of the images that TeXclip generates.
PBC implementation in equilibrium equation
Hi, guys,
Do some of you know how Periodical Boundary Condition is implemented in equilibrium equation while using FEM:
div{ C:sym[grad(u)] } = 0 ,where the displacement u is periodical.
Is there any (detailed) documentation about this stuff?
Thank you very much!
fracture mechanics
i want some one to clarify fundamental definition ,inter relationship or difference between the following terminologies .
small strain
large strain
small scale yielding
large scale yielding
software for eigenstrain problem
Hi,
Is there some fem code or software that can handle eigenstrain while solving equilibrium equation?
Thanks!
Need Help with Abaqus/Python Script
Hi,
I have a question on reading outputs in Abaqus. Is it possible to select apath using nodes without having to click on each node one at a time? Everytime I close Abaqus the path I create goes away and I have to create it again and again.
