Abstract: The effect of external mechanical stresses on the parameters of photoacoustic signals within Vickers indents in steel and nanocopper has been experimentally revealed. It has been shown that changes in photoacoustic signals can be reversible and irreversible, depending on the indent orientation and the stress applied to the sample. In this case, reversible changes can reach significant values at the level of tens of percent of the average signal from the sample. The relative changes in the photoacoustic signal amplitudes have been theoretically evaluated for indented and unindented areas, taking into account the temperature dependence of the elastic modulus of metals. It has been shown that its consideration allows qualitative explanation of the differences in the behavior of photoacoustic signals under stresses in indented and unindented areas.
