ON SURFACE MODELS WITH COUPLINGS AMONG THERMAL,ELASTIC AND ELECTRIC FIELDS

摘要：

We report a novel method to derive surface models of different orders, which account for the couplings among thermal, elastic and electric fields. The derivation is based on the state-space formalism, during which an operational interpretation of related partial differential operators is needed. For the degenerated case of a plane surface boundary of an elastic body, the results are identical to the well-known surface model proposed by Gurtin and Murdoch when the residual surface stresses are absent. Numerical results are given to show the surface effect on the propagation characteristics of the Bleustein-Gulyaev waves in a surface electroded piezoelectric half-space.
