An extension of the method used by the authors [e.g.: ibid. 22, No. 11, 105-111 (1986; Zbl 0621.73018)] is proposed here to determine the effective characteristics and stress concentrators on inclusions of inhomogeneous physically nonlinear media. The solution of this problem is obtained under the assumption of homogeneity of the tensor characterizing the nonlinear properties of the material within each inclusion and matrix.
