The Elastoplastic Impact Process Study of the Indenter and the Plate Lying on the Base

Abstract

The massive body impact on a uniformly stretched pivotally supported rectangular plate on an elastic Winkler base and on an endless plate lying on the surface of an ideal incompressible fluid is investigated. The asymptotic behavior of the Green influence function is used. The elastoplastic impact solution is in good agreement with numerical calculations and experimental data. The results to study the material properties are used when an indenter impacts ice.

The Elastoplastic Impact Process Study of the Indenter and the Plate Lying on the Base

“…In the case of the elastoplastic local collapse α (P), the normal impact of a mass body m moving at a speed V0 in the rectangular plate center of thickness h uniformly stretched (compressed) in its plane by the forces of p0 and lying on the Winkler basis with the coefficient of subgrade resistance k0. The impact on a uniformly stretched (compressed) plate on the base was investigated in [2][3][4][5][6] for the case of a rectangular plate, and in [3] the problem of striking a circular plate on an elastic base and an infinite plate on an incompressible liquid base was additionally investigated.…”
