Quasistatic delamination of sandwich-like Kirchhoff-Love plates
A quasistatic rate-independent adhesive delamination problem of laminated plates with a finite thickness is considered. By letting the thickness of the plates go to zero, a rate-independent delamination model for a laminated Kirchhoff-Love plate is obtained as limit of these quasistatic processes. The same dimension reduction procedure is eventually applied to processes which are sensitive to delamination modes, namely opening vs. shearing is distinguishe
A comparison of delamination models: Modeling, properties, and applications
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

Energetický prístup riešenia problému delaminácie v šmykovom móde na rozhraní s kohéznym a adhéznym kontaktom
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
