Re: [Getfem-users] Self-contact

[Yves Renard]

Dear Artur Pozniak,


A general contact algorithm for nonlinear elastostatics has been implemented in Getfem (based on field extension) but is not working for the moment.
 This will probably take still some time to stabilize it and make it reliable. Normally, concerning elastodynamics, this won't be a great difficulty to adapt some stable strategies for the approximation of contact in dynamics once the general contact algorithm will be finalized.
Notes, that the contact bricks with non-matching meshes developped by Konstantinos Poulios are already able to take into account some complex contact situations, but a priori in the framework of small deformations.

Dear GetFEM Users,

I am wondering if GetFEM is able to deal with very general contact algorithm.

In Abaqus/STANDARD there is a general contact routine, which detects ANY cases of contact w/o necessity of defining contact pairs.

I model densification of porous materials and such feature implemented in opensource library would be extremely useful. Is this possible in GetFEM?

If so, would it be applicable to nonlinear elastodynamics?

Thanks in advance,

Artur Pozniak
