| dc.description | Using a recently developed continuum theory of dislocation dynamics, we derive three new predictions about plasticity and grain boundary formation in crystals. (1) There will be a residual stress jump across grain boundaries and plasticity-induced cell walls, which self-consistently acts to form the boundary by attracting neighboring dislocations; we derive the asymptotic late-time dynamics of the grain-boundary formation process. (2) At grain boundaries formed at high temperatures, there will be a cusp in the elastic energy density. (3) In early stages of plasticity, when only one type of dislocation is active (single-slip stage I plasticity), cell walls will not form; instead we predict the formation of jump singularities in the dislocation density. | |
