The paper propose a method for determining of the parameters of the exponential shear modulus of a functionally graded half-space based on the solution of the problem of a pure shear of an elastic functionally graded half-space by a strip punch. The solution of the integral equation of the contact problem is constructed by asymptotic methods with respect to the dimensionless parameter. The dependence of contact stresses on the parameters of the shear modulus is analyzed. The determination of the parameters of the shear modulus of a functionally graded half-space is based on the values of shear stresses at the contact. By choosing proper shear modulus parameters of the functionally graded half-space, “approximately homogeneous” area inside of the functionally graded half-space are developed.
