Hello, I was curious if Firedrake is capable of solving elastoplastic problems. Right now I am trying to create a simple wave using Fenics Solid Mechanics app in elastoplastic media (without any success). I was wondering is Firedrake has a more user friendly platform for such problems. Thank you, Sincerely, Chaitanya

We currently have no special support for solving plasticity problems, where you need to solve for the implicit constitutive laws and updates and quadrature points. It is likely that you would have to write lots of code by hand. This is something that fenics solid mechanics is meant to do. So it is very unlikely that we are more user friendly in that direction. Cheers, Lawrence
Tomasz Salwa has implemented linear elasticity coupled to linear water waves and will likely implement nonlinear hyper elasticity in the near future. That is, however, still simpler that elastoplastic behaviour, I think. We will "simply" find a FEM descretization based on the VP for this nonlinear problem. We already wrote down the coupled and nonlinear equations in a short conference proceeding. Incidentally, Tomasz, could you give Firedrake the two reviewed conference proceeding references, please? --Onno ________________________________________ From: firedrake-bounces@imperial.ac.uk <firedrake-bounces@imperial.ac.uk> on behalf of Lawrence Mitchell <lawrence.mitchell@imperial.ac.uk> Sent: Wednesday, May 11, 2016 5:14 PM To: firedrake@imperial.ac.uk Subject: Re: [firedrake] Elastoplastic problems Dear Chaitanya,

Hi, Following Onno's request, one proceeding paper is available here: http://www.iwwwfb.org/Abstracts/iwwwfb31/iwwwfb31_39.pdf The other one will be published online on June 17, 2016.

Thank you for your response. Didn't get what I was looking for but the coupled water waves and linear elasticity project looks awesome! Love it. Sincere Regards, Chaitanya
