    This contribution presents recent results in the modeling and the analysis of delamination problems. It addresses adhesive contact, brittle, and cohesive zone models both in a quasistatic and a viscous, dynamic setting for the bulk part. Also different evolution laws for the delaminating surface are discussed

    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.V príspevku je popísaný nový model porušenia rozhrania viacvrstvovej štruktúry. Koncept riešenia predstavuje navrhnutý matematický model porušenia kontaktu na rozhraní. Navrhnuté numerické riešenie využíva rýchlostne nezávislý vývoj napätí a energetický koncept riešenia. Energetická formulácia riadi proces delaminácie prostredníctvom dvoch parametrov rozhrania. Prezentovaný príklad demonštruje teoretický prínos v oblasti aplikácie v inžinierskej praxi
