Wedging of an Elastic Medium with the Formation of Separation Zones / Zvyagin A.V., Romashov G.A. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2011. № 4. P. 33-39 [Moscow Univ. Mech. Bulletin. Vol. 72, N 2, 2017. P. 0].

The problem of motion of a rigid body in an elastic medium is solved analytically for the case when a separation zone caused by asymmetry is formed in front of the body. A scheme of flow around wedge-shaped and ogive bodies is given for the entire range of the velocities under consideration. It is shown that there exists a limit velocity such that the separation zone disappears when the body moves at a velocity greater than the velocity of transverse waves. The forces exerted on a wedge-shaped body and on an ogive body are the same in the case of the limit velocity.

Key words: contact fracture, theory of elasticity, dynamics.
