摘要: Debonding of coatings from substrate due to coating compression occurs in many engineering applications. A simplified analytical approach for the estimation ultimate leading debonding is developed this paper, assuming an assigned out-of-plane defect coating. The formulation based on solution a beam Pasternak (two parameters) elastic foundation, and assumption Mode I cohesive failure coating-substrate interface. resulting formulas are simple require knowledge limited number parameters.
