The work is focused on a detail study of the processes of stress and deformation states during instrumented nanoindentation, scratch and tribological tests in the coated composite systems using finite element modelling (FEM) externded FEM (xFEM) and Cohesive Zone Model (CZM) methods and subsequent experimental verification. The work will be performed on thin coatings on substrates with different mechanical properties. The aim is to understand the details of damage mechanisms in coatings in dependence on the loading conditions as well as the optimization of the conditions for the measurement of the mechanical properties and tribological properties of the studied coatings.
Aim: Detail study of the stress and deformation states during instrumented nanoindentation, scratch and tribological tests in the composite systems coating/substrate using finite element modelling (FEM)
Keywords: : Finite Element Modelling (FEM), nanoindentation, scratch test, friction test, ceramic coatings.
