An experimental deformation analysis of a grain aggregate is presented as well as a finite element method (FEM) which enables to compute some particular quantities which cannot be easily obtained experimentally, like the stress state and the stored energy of cold work. Comparisons are made between OIM measurements after deformation and FEM results performed on a mesh that matches exactly the original grain shapes and orientations before deformation. A very good agreement is found, especially intragranular microstructures are well predicted.
