Contact/Large Strains?

Is Code Aster capable of modelling plastic deformation processes such as cold rolling and wire drawing? On other words, does CA do contact & large strains well? I though I saw mention of such capabilities somewhere, but with few English docs, the learning curve is quite steep!

Hello,

Code_Aster is capable of modelling large displacements, large strains with very complex elasto-visco-plastic constitutive behaviours. Several contact modelling technics are also included in the solver.
You can simulate these kind of problems with either implicit non-linear statics or with explicit non-linear dynamic solver.

Concerning the learning curve: you are right, the french documentation is a major problem for the non-french speaking users. To compensate, we will publish several tutorials / examples & analysis templates on more and more advanced topics, like for example contacts, plasticity, modelling of assemblies, modal analysis, thermo-mechanics etc... so \"stay tuned\" for further news.

The Impact project (available on sf.net) is another open source solution for non-linear explicit dynamics but is limited to relativelly small scale problems (coded in JAVA).

Thanks much for your reply. I'll eagerly \"stay tuned\" for upcoming tutorials for CA! I really appreciate your efforts to make CA more usable for the non-Frech speaking community!

I've looked at Impact, but it is very limited in its capabilities and is very slow. Marc and LSDyna3D are very capable of simulating metal forming applications in Linux, but are also very expensive. It will be nice to have a GPL product that do complex analysis, also.
