Abstract : This paper presents the interactions of a simple vibrating beam host with embedded arrays of micro-actuators. The geometry of the micro-actuator is idealized to be ellipsoidal and Eshelby's classical techniques are used to obtain a first order estimate of the interaction energy of the actuator and the surrounding host, as a result of actuation loads. Preliminary analytical results for piezoelectric actuators embedded in an isotropic host provide important clues regarding the influence of the number of embedded transducers and the excitation voltage on the natural frequencies of the structure. The strain concentration in the host due to the embedded actuators is obtained by using Eshelby's classical result. The results of this study provide crucial insights for: (1) integrating the response of the host and actuator for transient analysis of the adaptive structure; (2) obtaining accurate transfer functions for transient analysis and control of the structure; and (3) assessing the damage (and associated loss of reliability) caused to the host and to the actuator by external as well as actuation loads.
