Nonlinear elasto-(visco)-plasticity for finite-strain deformations in geodynamics applications

Interviene:
Prof. EDIE MIGLIO
Politecnico di Milano

In many geodynamic applications the lithosphere has to be considered as a compressible elastic material, which can also flow viscously or break in a brittle fashion depending on the stress level applied and the temperature conditions. This talk will introduce a flexible methodology to address the complex material response, which imposes severe challenges on the discretization and rheological models used. The model is implemented in a parallel (MPI + multi-thread) 3D C++ code based on Deal.II library. Some numerical results will demonstrate the effectiveness of the proposed algorithm.
