| Abstract: | The pyroelectric materials play an important role in smart materials and structure system. This poper presented all kinds of the variational principles for the materials, which are significant in fundamental theory and applications of numerical approach. As examples, the control equation and boundary condition of anisotropic plate were derived from the potential variational principle under some assumptions. |
