摘要：
This paper describes a study of buckling and supercritical behavior of inhomogeneous coatings. A change in the first critical load value at which buckling occurs is studied as a function of the problem parameters on the basis of the variational interpretation of the problem and the Ritz method. Calculations are carried out for inhomogeneous coatings of two types: those with piecewise constant stiffness and those with continuously changing stiffness having a maximum inside and outside the delamination zone. The supercritical behavior of the coating is studied.
