BOND STRESSES IN CIRCULAR PIEZOCERAMIC BENDERS

摘要

An upper bound is obtained for the normal and shear stress distributions acting at the bond interface of circular piezoceramic flextural mode transducers. Results are valid for large thickness/ radius ratios due to the nonlinear character of the analysis. Computations for PZT-4 benders indicate that there is little probability for bond failure under normal loading and bonding conditions.
