Piezoelectric devices, such as piezoelectric traveling wave rotary ultrasonic\nmotors, have composite piezoelectric structures. A composite piezoelectric\nstructure consists of a combination of two or more bonded materials, where at\nleast one of them is a piezoelectric transducer. Numerical modeling of\npiezoelectric structures has been done in the past mainly with the finite\nelement method. Alternatively, a finite volume based approach offers the\nfollowing advantages: (a) the ordinary differential equations resulting from\nthe discretization process can be interpreted directly as corresponding\ncircuits and (b) phenomena occurring at boundaries can be treated exactly. This\nreport extends the work of IEEE Transactions on UFFC 57(2010)7:1673-1691 by\npresenting a method for implementing the boundary conditions between the bonded\nmaterials in composite piezoelectric structures. The report concludes with one\nmodeling example of a unimorph structure.\n
