CHARACTERIZATION OF INTERFACIAL ADHESION PROPERTIES OF DUCTILE MATERIALS: A CROSS-SECTIONAL NANOINDENTATION METHOD

Cross-sectional nanoindentation is a recent method for adhesion measurement for coating and substrate systems with dissimilar material parameters. In the present work, finite element simulation with the cohesive elements is used to combine with the cross-sectional nanoindentation test to characterize the adhesion of two dissimilar elastic-plastic materials. The objective of this study is to determinate the relationship between the indentation responses, materials mechanical properties and the interfacial adhesion energy. It is suggested that these relationship can be potentially possible used to extract the interface adhesion properties of a film/substrate system.
