牛顿力学基础
On Foundations of Newtonian Mechanics
摘要:
本文在Konoplev公理化方法的基础上,拓宽了连续介质力学的研究领域,将连续介质力学与经典力学结合起来,形成一种新的力学系统理论。导出了质点、多体系统和连续体的“抽象”力学系统的运动方程:牛顿-欧拉方程、第二类拉格朗日方程和Navier-Stokes方程。准线性本构方程的引入符合V. Konoplev的定义的应力和应变(率)矩阵。
英文摘要:
Being based on V. Konoplev's axiomatic approach to continuum mechanics, the paper broadens its frontiers in order to bring together continuum mechanics with classical mechanics in a new theory of mechanical systems. There are derived motion equations of `abstract' mechanical systems specified for mass-points, multibody systems and continua: Newton-Euler equations, Lagrange equations of II kind and Navier-Stokes ones. Quasi-linear constitutive equations are introduced in conformity with V. Konoplev's definition of stress and strain (rate) matrices.
