As can be seen from the above graphs, an increase in the degree of treatment of the restorative operation, especially since the quality is higher. When increasing the parameter shortening of cracks and the weakening of the shielding effect of the interaction of parallel defects.

there is a change in the mechanism of destruction (transition from one crack tip to another). This, for example, is evidenced by the breaks in the curves. Comparison of Fig. 3 and Fig. 4 shows that non-contrast healing of surface cracks near the edge of the body is generally more effective than healing near the tips of the defects. 4. Conclusions The paper developed a model of crack healing with a non-contrast material in bodies with surface defects. In analytical and numerical form, quantitative estimates of healing efficiency are established depending on three parameters: degree of filling of cracks, crack resistance of the newly formed interface, mutual location of cracks. Body restoration near the surface is shown to be generally a better solution than healing near the defect vertices. Similar problems about the influence of partial healing on the limit equilibrium of plates with edge contact cracks under the conditions of bending or bending with tension can be considered on the basis of the model of the contact of
