Introduction,Classical continuum mechanics considers material continua as point-continua with points having three degrees of freedom, and the response of a material to the displacements of its points is characterized by a symmetric stress tensor. Such a model is insufficient for the description of certain physical phenomena.

Balance and Conservation Principles,The differential equations of motion in classical continuum mechanics are usually derived from the law of conservation of mass (equation of continuity), and from the Euler’s laws of balance of momentum and moment of momentum. Since we postulate here the validity of these laws, we regard them as principles.
