Abstract
In this paper we review some of the modelling and experimental techniques recently developed for the analysis of the macro- and meso-scopic behaviour of polycrystalline aggregates. We discuss the use of a joined-up approach for the assessment of polycrystalline materials at macroscopic and grain level based on combining modelling using crystal plasticity finite element (CPFE) with experimental characterisation by in situ loading with continuous lattice strain measurement by diffraction. The complementarity of the two methodologies is emphasised as a means of improving our understanding of the physics underlying inelastic deformation, damage mechanisms and fatigue crack initiation. The proposed approach is built into a general framework which enables reliable and accurate determination of the inhomogeneous fields of plastic strain, the identification of regions of localised plasticity, and intergranular residual stresses. Examples are given of how microscopically calibrated CPFE simulations could be used to predict the evolution of lattice stresses and strains in advanced structural alloys of industrial interest.
