Abstract :
A bimorph cantilever consisting of two oppositely polarized piezoelectric elements, fixed at one end, and loaded by a discrete mass at the other, is considered. It is regarded as driven by any combination of end force, end moment, surface pressure, and voltage. Its responses consist of end deflection, end slope, volume displacement, and electric charge. The dynamic admittance matrix of the structure is developed assuming simple Euler-Bernoulli beam theory applies
