Permanent deformation of a sort that depends mainly on time of exposure to a stress, and that tends to increase significantly with time of exposure, is called viscous or creep deformation and materials which exhibit that, as well as tendencies for elastic response, are. However, the major limitation of micromechanics is that the medium is assumed to be infinitely extended no boundary and the geometry of the microstructure is strictly limited, thus making it inconvenient to accurately represent actual composite materials.
