This paper presents a full-field analysis of size dependent crystal plasticity according to two robust and efficient ways to account for microstructural internal length effects in the constitutive laws. Both consist in introducing a Hall–Petch term

The refinement of grains in a polycrystalline material leads to an increase in strength but as a counterpart to a decrease in elongation to fracture. Different routes are proposed in the literature to try to overpass this strength-ductility dilemma,
