Effets de textures cristallographique, morphologique et topologique sur la conduction effective d'un milieu hétérogène

Abstract : A new self consistent approach theory is formulated in the case of the electrical conductivity in the polycrystal. A self consistent approach is developed, where each grain is assumed to be a single ellipsoidal inclusion in a homogeneous equivalent medium. An interaction formula is derived and the electrical conductivity is calculated by resolving a linear system of equations. Applications to morphological and crystallographic effect are considered. We discuss in some details the contribution of our approach to the study of electrical conductivity of a composite medium constituded, for example, by spherical inclusions of conductivity k1 in a matrix of conductivity k2
