Re: [deal.II] About metallic ductile damage

[Jean-Paul Pelteret]

Dear Itachi,

To supplement what Bruno has already mentioned, deal.II provides some of the 
tools what you might find useful to implement constitutive laws or specific 
governing equations. To get some feeling as to what is possible, I would 
suggest that you take a look through the list of publications 
 to see what the community has achieved 
using deal.II. There are also several tutorials 
 and code-gallery 
contributions  (current and pending) 
that might give you insights into how you might go about implementing such a 
constitutive law within a solid-mechanics code. You might also with to look at 
the “Applications” listed in the top bar on the home page  
(I can’t give you a clickable link, I’m afraid). I believe that at least one of 
them (PRISMS) has a partial focus on plasticity.

Best,
Jean-Paul

[deal.II] About metallic ductile damage

[itachi Ezio]

Hi,

I'm Abaqus user and fresh new about using deal.II. I'd like to ask a few 
questions base on deal.II functions.

I'm looking for the simulation for metallic ductile damage behavior with 
deal.II ( for example with triaxiality and lode angle), is it possible?

And how is it like to write user materials in deal.II, especially in 
plasticity behaviors? Is it also quit sophisticated as in UMAT in Abaqus?

Looking forward to the answers, thanks for that!
