Application elasticPlasticSolidFoam Description Transient/steady-state segregated finite-volume solver for small strain elastic plastic solid bodies. Displacement increment field DU is solved for using a total Lagrangian approach, also generating the strain tensor field epsilon, the plastic strain field epsilonP and stress tensor field sigma.
