Question about stochastic Finite Elements

tlaverne's picture

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 Thomas,

you'll find a short list on SFEM software in chapter 3.6 of the following paper: http://dx.doi.org/10.1016/j.cma.2008.11.007

There seems to be a probabilistic toolbox in the recent ANSYS release. Also COSSAN, NESSUS and FERUM are mentioned with references in this survey. From my point of view this paper summarizes nearly every method of SFEM except non-probabilistic ones. Therefore I'll include some papers in the following.

In general search for "Stochastic FEM" (SFEM), "Finite Element Method for Stochastic Problems" (FEMSP) and "Spectral Stochastic Finite Element Method" (SSFEM). I don't know, if this is interesting too: Fractal Finite Element Method (seems to be used mainly in fracture mechanics).

Probabilistic SFEM:

If you are interested in non-probabilistic FEM search for "David Moens and Dirk Vandepitte":

You should definitely have a look at this journal:

Finite Elements in Analysis and Design

http://www.sciencedirect.com/science/journal/0168874X

 

Maybe you'll find help also in this special issue of Computer Methods in Applied Mechanics and Engineering:

http://www.sciencedirect.com/science?_ob=PublicationURL&_tockey=%23TOC%235697%232005%23998059987%23574696%23FLA%23&_cdi=5697&_pubType=J&view=c&_auth=y&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=8ea2a39e736e1de18e64dcaf18b16826

Hope I could help,

Martin

Thank you very much Martin !

I knew that COSSAN was actively developped and that many consulting was done with it, even though no commercial release is available for now. I will check the probabilistic toolbox for ansys. Thank you for the references as well ! There are some of them that I was not aware of, so it should help !
