An energetic approach for interface delamination problem in sliding mode with cohesive or adhesive contact

Abstract

A new interface delamination model of a layered structure is discussed. The concept of the solution is developed by the mathematical model of interface contact damage. The proposed numerical solution considers the rate independent evolution at small strain and the concept of the energetic solution. Applied energetic formulation governs the debonding process by means of two interface variables. Presented numerical example demonstrates its theoretical applicability of the whole solution approach in the engineering practise.
