- Аннотация: The role of low-amplitude oscillations in the formation of mechanical properties of nanocontacts with different values of the ratio of hardness H to the elastic modulus E was studied by dynamic nanoindentation (DNI). Various methods for processing raw data and extracting nanocontact characteristics from them have different sensitivity to low-amplitude oscillations of the load. It is found that under certain test conditions, the addition of low-amplitude oscillations does not affect the mechanisms, kinetics and magnitude of the plastic deformation of the material under the indenter. The threshold values of the oscillation amplitude for materials to soften locally in the nanocontact interaction are determined.
