ON THE EXTENSION OF CLASSICAL MECHANICS, WHEN STRUCTURING BODY TAKING INTO ACCOUNT

Abstract

Abstract. A summary of the mechanics of structured bodies is submitted. In contrast to Newtonian mechanics, the mechanics of structured bodies allows us to describe the origin and evolution of nonequilibrium systems. The mechanics of the structured bodies is based on the fact that all bodies in general are an open nonequilibrium systems, and any such system in the approximation of local thermodynamic equilibrium can be represented as a set of equilibrium subsystems. As a model of such of the equilibrium subsystem a system of potentially interacting material points (MP) can be used. We call it structured particle (SP). The motion equation is derived from the SP’s dual energy expression, which consist from the sum of the motion energy of SP and its internal energy. The irreversibility of SP dynamics allows us to introduce into the classical mechanic the concept of dynamic entropy. The nature of the differences between from the SP mechanics and MT mechanics is explained.
