摘要
The methodological aspects of studying the time-dependent mechanical properties of materials subjected to nanoindentation under pulsed loading and unloading of a Berkovich indenter are considered. It is shown that the viscosities and relaxation times of viscoelastic materials can be determined from nanoindentation experiments. The advantages of the pulsed nanoindentation technique are demonstrated with the photoplastic effect in chalcogenide glasses.
