Explicit expressions of the generalized Barnett-Lothe tensors for anisotropic piezoelectric materials

Similar to the case of two-dimensional anisotropic elasticity, the three ge neralized Barnett-Lothe tensors L, S and H, are frequently encountered in t he extended Stroh formalism of two-dimensional deformations of anisotropic piezoelectric materials. Due to its implicitness, the extended Stroh formal ism cannot be easily employed to obtain the tensors L, S and H in an explic it form. In this paper, explicit expressions of these generalized tensors f or anisotropic piezoelectric media are obtained using the modified Lekhinit skii formalism for piezoelectricity. As an example, the explicit expression s for L, S and H of transversely isotropic piezoelectric materials are pres ented. (C) 2001 Elsevier Science Ltd. All rights reserved.
