Numerical modeling of micro-profile deformation under orthogonal action depending on loading conditions. Part 1

The processes of local surface plastic deformation of machine parts are considered. It has been established that the real surface of machine parts after blade processing has a predominantly wedge-shaped (triangular) profile in the longitudinal direction. It is shown that the mechanism of microprofile shaping, due to its irregular nature, etc., has not been sufficiently studied. The mechanism of the shape change of the microroughness model at the degrees of deformation comparable to the height of the initial micro-profile has been established. The influence of the degree of micro-profile settlement on the angle at the base of the deformed micro-profile, the relative width of the contact surface, as well as on the behavior of the point of the micro-profile depression depending on the loading conditions is presented. A significant effect of loading conditions on the nature of deformation of the microprofile has been established.
