Biot [1], Lord & Shulman [4] and Sherief et al. [5] theories are used to develop the basic equations for porous piezothermoelastic with mass diffusion material. The variational principle, uniqueness theorem and theorem of reciprocity in this model are established under the assumption of positive definiteness of elastic, porousthermal, chemical potential and electric field.http://jsm.iau-arak.ac.ir/article_523200_fd05a2c5f80ab6ca1c13afec98e22df4.pdf
