Abstract :
The static response of an intelligent beam with surface-bonded piezoelectric patches is investigated in this paper. Timoshenko beam theory is employed to study the properties of beam-like structures bonded with multiple pairs of PZT patches. Here, only one-dimensional axial deformation of PZT wafers is considered. A shear lag model is adopted to simulate the interfacial bonding between PZT patches and the host beam. The static behavior of the smart beam is then given in detail based on a transfer matrix method. Furthermore, the actuation mechanism of the piezoelectric patches is also studied, considering the effects of the interfacial properties between the piezoelectric patches and the host elastic beam.
