Is deal.ii suitable for civil engineering problems?

[alan...@gmail.com]

I am taking the FEM course on coursera sponsored by u-mich. I just installed deal.ii and successfully ran the first example. I am quite happy with that, but before learning more, I want to make sure how suitable is deal.ii for me (in the professional aspect, I am a civil engineer) and how much I can achieve with it.

a) Is it possible to include any material constitutive relation, for example, Todeshini Stress-strain relationship (Figure b) ?

b) is it possible to work with frame/bar elements in 1D, 2D and 3D, not only on compression or tension loads (which I know deall.ii is capable of), but also being capable of describing the flexural behavior, this is, is deal.ii capable of modeling a Bernoulli Beam?
c) is it possible to model shell elements in 2D and 3D (and as before), not only for compression/tension (or plane stress/strain problems), but also modeling it's bending behavior, like a bending plate.

d) Is it possible to model hysteric behavior?

Hi,

Deal.II has been used in numerous applications, including but not limited to solid mechanics,

see publication lists http://www.dealii.org/publications.html 

and also publications of my colleague Jean-Paul https://ltm-en.cms.rrze.uni-erlangen.de/person/pelteret-jean-paul-ph-d/

who is focused on solid mechanics and multi-physics problems.

deal.II works with weak forms, so it's agnostic to the origin of PDE and thereby you can introduce whatever 

constitutive equation to close the system. But you would need to implement it yourself.
