Material evolution of defective composites

Beyond the defective structures (or inhomogeneities) occurring in bodies made of a single constituent, composite materials may exhibit different kind defectivity arising from fact that, even if each constituent is defect-free, incompatibility between them detectable entity. After defining rigorous tensorial measure density these defects, law for its material evolution proposed whose driving force presence itself. The model illustrated with numerical solutions properly formulated initial boundary value problems systems partial differential equations.
