Abstract
The purpose of the study is to substantiate a fundamentally new approach to the theory of soil cutting, based on the replacement of the classical point force method on the cutter of the excavating machine working body to the distributed pressure on it. This approach is a more accurate method for describing the deformation processes occurring in the excavated soil by the earth-moving machine and the response to the condition of its working body. This interaction will make it possible to improve the working bodies of earth-moving machines to ensure more efficient modes of operation. The analysis of soil resistance forces calculations for different soil destruction schemes is carried out. On the basis of the review analysis the goals and tasks of the research, which include the development of a mathematical model of shock wave propagation on the ground, a numerical experiment in the Abaqus software package, and experimental verification of the obtained results, have been formulated
