The velocity and the rate of decay of a strain wave in a layer of a viscoelastic material rigidly fixed on a solid foundation
are determined. The wave structure (ratio of the longitudinal to the transverse displacement) and the profiles of these displacements
are analyzed. Attenuation of waves in the first mode is found to be more significant than that in an infinite space. The most
intense decay is observed at resonance frequencies. A strong effect of compressibility of the medium on wave parameters is
revealed. Conditions at which such a system operates as a waveguide are found. For a loss tangent higher than 0.13 (for an
incompressible medium), the character of the dispersion dependence is observed to change drastically: the wave velocity decreases
with decreasing frequency.

The longitudinal and transverse components of deformation of the surface of a flat layer of a viscoelastic material glued
onto a solid base under the action of a traveling pressure wave are determined. The coating compliance is described by two
components corresponding to two components of surface displacement. The dimensionless compliance components depend only on
the viscoelastic properties of the material, the ratio of the wave length to the layer thickness λ/H, and the ratio of the
wave velocity to the velocity of propagation of shear oscillations V/C

. Data on the dynamic compliance are presented for 0.3 < λ/H < 30 and 0.1 < V/C
t

< 10. The compliance is demonstrated to be determined by its absolute value and by the phase lag of strain from pressure.
The effect of viscous losses in the material and compressibility of the latter on the dynamic compliance is analyzed. An anomalous
behavior of the compliance with the wave velocity being greater than a certain critical value is explained.

The experiments on recording the radiation decay signal of the GIR2 reactor core in the range from 0 to 40 µs when exposed to an external intense neutron pulse with a duration of ∼1 µs are performed. The reactivity interval from subcritical (−7.5 β) to critical (+0.28 β) states of the reactor is studied. It is found that the signal of the detector with a plastic scintillator depends on the reactivity and is proportional to the change in the density of thermalized neutrons in the reactor converter. The results show that the reactivity of the GIR2 reactor can be determined on the basis of measurement of the signal decay of a scintillation detector and the well-known expression $${\alpha _\infty } = {\beta \over \Lambda }(\rho - 1)$$ to calculate the reactivity values only for states with a reactivity greater than ∼−3 β. 相似文献
