Delamination of a Coating from an Elastic Substrate

Known models were used to investigate the delamination of a pre-compressed coating from an elastic substrate, to study in detail the corresponding transcendental equation, prove the existence of a solution in a certain range of parameters, and obtain simple formulas for the critical value The post-buckling behavior of the coating was studied using linearization and the Ritz method It was proposed to simplify the problem by solving the problem for a beam with Winkler type boundary conditions in the delamination region, and an assessment of this simplification was made.
