One of the hard open problems in mechanical engineering is the upscaling of large numbers of dislocations.
In this talk I will discuss the rigorous derivation of continuum dislocation density models and strain-gradient plasticity models from discrete and semi-discrete theories via Gamma-convergence.
I will also discuss progress and open problems in modelling dislocation interactions and dynamics.

This is based on work in collaboration with Marc Geers, Ron Peerlings, Mark Peletier and Maria Giovanna Mora.
