Title: | Strain gradient visco-plasticity with dislocation densities contributing to the energy |
Language (ISO): | en |
Abstract: | We consider the energetic description of a visco-plastic evolution and derive an existence result. The energies are convex, but not necessarily quadratic. Our model is a strain gradient model in which the curl of the plastic strain contributes to the energy. Our existence results are based on a time-discretization, the limit procedure relies on Helmholtz decompositions and compensated compactness. |
