Title: On the generalized canonical equations of Hamilton for a time-dependent mass particle.
Authors: Casetta, Leonardo1 lecasetta@gmail.com, Pesce, Celso1 ceppesce@usp.br
Source: Acta Mechanica. Dec2012, Vol. 223 Issue 12, p2723-2726. 4p.
Subjects: Hamilton's equations, Contact transformations, Meshcherskii, Vladimir Petrovich, kniaz', 1839-1914, Kinetic energy, Flux (Energy), Analogy
Abstract: Fundamental principles of mechanics were primarily conceived for constant mass systems. Since the pioneering works of Meshcherskii (see historical review in Mikhailov (Mech. Solids 10(5):32-40, ), efforts have been made in order to elaborate an adequate mathematical formalism for variable mass systems. This is a current research field in theoretical mechanics. In this paper, attention is focused on the derivation of the so-called 'generalized canonical equations of Hamilton' for a variable mass particle. The applied technique consists in the consideration of the mass variation process as a dissipative phenomenon. Kozlov's (Stek. Inst. Math 223:178-184, ) method, originally devoted to the derivation of the generalized canonical equations of Hamilton for dissipative systems, is accordingly extended to the scenario of variable mass systems. This is done by conveniently writing the flux of kinetic energy from or into the variable mass particle as a 'Rayleigh-like dissipation function'. Cayley (Proc. R Soc. Lond. 8:506-511, ) was the first scholar to propose such an analogy. A deeper discussion on this particular subject will be left for a future paper. [ABSTRACT FROM AUTHOR]
