Extremal Overall Elastic Response of Polycrystalline Materials

    Project Details


    A simple polycrystal is a composite material consisting of a mixture of a number of rotated crystals of the same anisotropic material. Based on a variational characterization of the effective material parameters, bounds on the energy in such polycrystals are calculated analytically in the form of what is referred to as optimal bounds, that is bounds which always hold and which cannot be sharpened. In the calculation no assumptions have been made concerning the symmetry of the polycrystal. The achieved energy bounds have also been compared to other bounds, achieved for crystals with certain material symmetries (e.g. isotropy).
