Abstract

A strain gradient crystal plasticity model is used to predict size effects for an FCC cube oriented block subjected to simple-shear loading conditions. A feature of the model is inclusion of the geometrically necessary dislocation densities necessary to satisfy the lattice compatibility and both short and long range dislocation interactions. The long range interactions define a back stress which introduces an internal length scale suitable for predicting material size effects.
