Conclusions
1. Investigations of physical modeling of pulsed actions on models of block media (with different material composition and characteristic dimensions of the subblocks) by energy-calibrated impacts confirmed the hypothesis expressed earlier by the authors about the possibility of existence of pendulum-type waves, the elementary carriers of which are geoblocks of a different scale level (μ-waves).
2. An analysis of the regularities of formation of the spectra of the wave packets and graphs of the absolute displacements of the blocks, determined by the optical method, permitted concluding a resonance mechanism of occurrence of μ-waves, underlying which is the canonical relationship of the spectral modes for wave packets with respect to factor (√2)i, i=0, ±1, ±2, ±3, ... .
3. The effect of the condition of canonical relationship of the spectrum in wave packets of μ-waves under certain conditions of energy actions can leads to the occurrence of the effect of anomalously low friction between interacting blocks (carriers of μ-waves) in directions orthogonal to the line of action of the external pulse.
