Abstract
A new method is described to determine the time-dependent elastoplastic and dissipative properties of solids in nanovolumes by recording the instantaneous values of the stress and depth of penetration of a rigid indenter. Measurements are also made of the energy W 1 supplied to the indenter, the energy U dissipated in the insertion process, and the energy W 0 returned to the indenter on unloading. Results of measurements of the dynamic microhardness and also of the energies W 0 and U for NaCl crystals are presented as functions of the duration of contact between the indenter and the surface for times between 1 ms and 10 s.
