...) leading to catastrophic failures. This quadratic actuation behavior of electrostrictive actuators is very different from that of piezoelectric actuators [( 6 )]. Examining the spatial modal actuations, one can further determine the maximal amplitudes of the three actuation components and the total modal...

... propagation due to multiple actuators can be determined by superimposing the waves generated by different actuators. The load transfer between piezoelectric actuators and the host medium under electric loading will be discussed in this section. Attention will be focussed on the effect...
