The influence of plastic properties of the surroundings on the interaction process of the “cylindrical body – External medium” system

The non-stationary shear interaction of a cylindrical body with the surrounding is discussed in article. A considered elastic, and medium modelled as an elastoplastic medium. conditions on contact surface are taken form Coulomb friction. two-dimensional problem numerically solved by finite difference method. Based results calculations, mechanism deformation energy redistribution formation friction forces change direction their action, well near-contact layer external body, shown. An increase wave parameters significant violation uniformity revealed. influence plastic properties process determined. Plastic strain observed particles close to which indicates existence during interaction; lead decrease amplitude maximum stress body.
