Abstract: Abstract Viscoplastic flow of polycrystalline metallic materials is the result of motion and interaction of dislocations, line defects of the crystalline structure. In the microstructural/physics-based constitutive model presented in this paper, the main underlying microstructural… read more here.

Abstract: This paper focuses on the connections between four stochastic and deterministic models for the motion of straight screw dislocations. Starting from a description of screw dislocation motion as interacting random walks on a lattice, we… read more here.
