Analysis of research on soil destruction criteria during its interaction with working bodies

Under the action of working surface tillage unit, three mutually perpendicular stresses and corresponding deformations occur in soil layer, which are characterized by different time functions. The finding these functional relationships is fundamental task agricultural mechanics, with help process crumbling physical mechanical properties can be described interaction bodies. article presents an analysis results studies domestic foreign scientists destruction its When considering from point view stress theory, Coulomb-Mohr theory most often used. It proposed to expand consideration adding elements strength that will describe rate change acting loads.
