During the last few years I have been actively working (mostly as part of my doctorate degree) in developing a solid dynamics toolkit within the framework of cell-centred and vertex-centred Finite Volume Method. This novel mixed formulation overcomes the drawbacks associated with conventional displacement-based Finite Element and Finite Volume formulations including equal order of convergence for stresses and strains, improved performance for nearly incompressible materials and elimination of hour-glassing modes. For practicality purposes, it was decided to implement the proposed framework in the popular CFD code OpenFOAM. I am pleased to announce the open source release of these toolkits via GitHub.

Does Openfoam software can simulate plastic deformation with good accuary ? Has Openfoam got plasticity models ?
