Using the continuum thermodynamics, it is found that the first law of thermodynamics contains a physical variational principle, which can be used as a fundamental natural principle to derive the governing equations in physics and continuum mechanics. This theory will be used to derive the governing equations of the discussed piezoelectric and pyroelectric body and its environment in Chap. 2.The Maxwell stress can be obtained automatically by the migratory variation of the electric potential.  In literatures many works on the static and dynamic generalized stress and displacement analyses in piezoelectric and electrostrictive materials with and without defects have been published. Some important results of piezoelectric materials will be collected, modified, and discussed in a unified version in Chaps. 3 and 4. The results of the electrostrictive, pyroelectric, and functional graded piezoelectric materials will be given in Chap. 5.more
