Conducted critical content - analysis of the theory of academician V. L. Baladinsky, in which the foundations of the modern theory of the destruction of soils and rocks are laid out. Unlike current theories, this theory in linear approximation takes into account the duration of destruction, the energy and loading speed, the velocity of deformation waves in the array, and the change of soil properties under stress. In such elastic oscillations, these equations describing the dynamic processes in the soils that are destroyed are linear, and in the case of finite residual deformations, they are nonlinear. In addition, the above theory of V. L. Baladinsky only in the first approximation takes into account the influence of the wave front (more precisely, the shape of this front), which is formed in the process of destruction of the cultivated soil. However, the advanced approach also determines the stresses between the working body and the front of the wave and can be used to estimate the rate of crack propagation when soil is destroyed. This, in turn, allows us to determine the regime and design parameters of single and multi-element working bodies of the earth ((soil tillage machines used in agriculture, based on the required volume of destruction of soil.References
