Some Special Problems of Solid Mechanics

Abstract

Among all the problems in solid mechanics a special place belongs to a problem of unsteady movement of rigid bodies with varying size and mass. General approaches to these problems are treated by Meshchersky and other authors. However, in doing so, one can obtain in some cases seemingly paradoxial results relevant to violation of the law of energy balance (see, e.g., Panovko 1985). To understand the nature of those paradoxes, the elastic properties of a solid need to be taken into account.
