Plastic flow is never a continuous process either in time or in space, yet it continues to be modelled in this way. The following topics will be discussed: the triumph and the failure of the Taylor model; the forest rules, OK?; distributed sources of dislocations; the perils of coarse-graining; how crystallographic is slip?; what practical consequences might flow from a sound theory of plastic flow?

This talk is part of the Surfaces, Microstructure and Fracture Group series.
