This paper provides a theoretical analysis of the elastic wave propagation in an elastic medium induced by embedded piezoceramic actuators under dynamic electric loads. A new actuator model involving the deformation in both the transverse and longitudinal directions of the actuators is used to study the wave propagation induced by multiple actuators. The resulting waveform is determined using a pseudo-incident wave technique and solving the resulting integral equations in terms of the interfacial shear stress and transverse displacement of the actuators. Numerical simulation is conducted to evaluate the effects of the geometry, the loading frequency, and the interaction between actuators upon the resulting wave propagation.
