A variational approach to electroelastic analysis of piezoelectric ceramics with surface electrodes. (English) Zbl 1005.74023
From the conclusion: We obtain a generalized variational principle from which the well-known Hellinger-Reissner principle and Hu-Washizu principle of elasticity can be obtained if the electric effect is not taken into consideration.
