Dynamical effects induced by static elastic loading of solid bodies

Experimental data on two known effects arising in response to an adiabatic elastic loading of solid bodies are presented. These are the thermoelastic effect, which consist in a change in temperature upon loading, and the frequency-elastic effect, which consists in a change in the frequency of vibrations of atoms upon loading. Similar and dissimilar features of these two effects are indicated. The mechanisms of the effects are discussed, and the degree of their interplay is revealed. The frequency-elastic effect is found to play a leading role. The temperature effect appears to be a quantum consequence of the change in the frequency of vibrations of atoms because of the anharmonicity of atom-atom interaction. Energy features of both effects are discussed.
