Nonclassical continua, pseudobalance, and the law of action and reaction

摘要: The procedure followed in constructing models for gene- ralized continua is revisited. It shown that the microforce ba- lance equations required description of generalized are not fact expressions balance physical quantities, but consequences regularity assumed systems contact actions. In proposed approach law action and reaction, which classical continuum mechanics a consequence Euler's laws, recovers status basic principle held Newto- nian mechanics. Some examples taken from literature discussed.
