Abstract

New principles of work and energy as well as power and energy rate with cross terms for polar and nonlocal polar continuum field theories were presented and from the mall corre sponding equations of motion and boundary conditions as well as complete equations of energy and energy rate with the help of gener alized Piola.s the orems were naturally derive dinall and without any additional requirement.Finally,some new balance laws of energy and energy rate for generalized continuum mechanics were established.The new principles of work and energy as well as power and energy rate with cross terms presented in this paper are believed to be new and they have corrected the incom-pleteness of all existing corresponding principles and laws without cross terms in literatures of generalized continuum field theories.
