Comments, with reply, on ;Characterization of piezoceramics' by M. Brissaud.
The commenters note that when M. Brissaud, in the above-titled paper (see ibid., vol.38, no.6, p.603-617, 1991), attempted to solve several piezoceramic bar, plate, and disk problems by superposition of bulk longitudinal waves, he neglected the shear wave contributions. Therefore, the commenters suggest that his solutions do not satisfy the appropriate stress-free boundary conditions. Brissaud, responding to the comments, discusses the validity of the models used.
