Abstract
The article considers numerical and analytical methods for assessing vibration protection properties of various types of obstacles in the ground, and the choice of the optimal structure of a vibration-absorbing obstacle based on the obtained results. For this purpose, a non-stationary effect induced in an elastic medium with a different geometry of the incident wave is specified. The functions of the influence of displacements and stresses in an elastic half-space are determined for a unit field of displacement of the half-space boundary. The problem of wave passage through an obstacle is solved, with the Kirchhoff-Love plate and the three-layer plate of V.N. Paimushin used as a model. The stresses and displacements of the medium after passing the obstacle are determined. The analysis of vibration-absorbing properties of homogeneous obstacles and obstacles of complex design under the influence of attenuated waves of different geometries is performed. As a result, their effectiveness is estimated.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
