The article examines the destruction of a composite using a diamond disk. The composite structure is adopted as a two-factor symmetric model, in which the composite grains are represented as balls in the matrix body. A feature of the design is the symmetry of the crack along the two main planes. A model of interaction of a diamond disk with a composite is developed. The destruction of composite models was carried out by cutting the individual bands. Cutting revealed the cyclical nature of the energy characteristics of the fracture models. The cyclic nature is described by a sinusoidal wave of structure destruction. The simulation results provide a formula for the composite structure, which is described using the energy characteristics of cutting. The structure and parameters of the fracture model obtained during cutting allowed us to fully describe the composite structure model. The results of modeling show that it is possible to fully describe the model of a concrete composite using only the energy parameters obtained during cutting of the material.
