Abstract: Active damping in a smart cylindrical shell using piezoelectric sensors/actuators is studied. The electrodes on the sensors/actuators are spatially shaped to reduce spillover between circumferential modes. A three-noded, isoparametric, semianalytical finite element is developed and used to model the cylindrical shell. The element is based on a mixed piezoelectric shell theory that makes a single layer assumption for the displacements and a layerwise assumption for the electric potential. The effects of axial and circumferential mode number, length to radius ratio, radius to thickness ratio of the shell, percentage of the area of the shell covered with piezoelectric material, and the location of the collocated sensor/actuator on the shell on the active damping ratio of the shell are studied.

Abstract: This paper gives a bibliographical review of the finite element methods (FEMs) applied to the analysis and simulation of smart materials and structures. The bibliography is an addendum to the Smart materials and structures—a finite-element approach: a bibliography (1986–1997) published in 1998 Modelling Simul. Mater. Sci. Eng. 6 293–334. The added bibliography at the end of this article contains 977 references to papers and conference proceedings on the subject that were published in 1997–2002. The following topics are included: smart materials, smart components/structures, smart sensors and actuators, and controlled structures technology.
