As a computational model of deformation of wedge-shaped gradient coatings lying on a non-deformable base, we propose a solution of the contact problem for a wedge non-uniform in thickness rigidly fixed on the lower face. A closed analytic solution of the contact problem is obtained for the case of elastic moduli (Young’s modulus, Poisson’s ratio, shear modulus), which is a continuous differentiable function with respect to the angular coordinate. The influence of the gradient of the wedge on the distribution of contact stresses under the stamp is illustrated. The problem is posed in connection with the need to predict the phenomenon of delamination of modern coatings of a complex structure from a nondeformable substrate.
