1. A material model for a set of microstructural entities in a surrounding matrix material being initially in equilibrium prior to application of an applied load comprising grains, particulates and particles each being aligned at a corresponding angle with respect to the applied load such that in response to the applied load each of said entities rotates though a corresponding angle to remain in equilibrium and to create induced stresses in surrounding matrix material and in the interior of the corresponding entity that arise from strain on the matrix material resulting from the rotation of the entity.
