A power series solution is presented for the static equilibrium equations of an axisymmetric composite cylinder under loadings due to surface mounted or embedded piezoelectric laminae. Both uniform and nonuniform distributions of the piezoelectric effect are studied and results are verified using a finite element model based on axisymmetric two-dimensional elasticity theory equations. A cylindrical truss element actuator is developed which may be used for damping vibrations of truss-type structures. Finally, the effects of a piezoelectric patch have been investigated. The axial forces generated at the fixed ends of a cylinder are found to be proportional to the length of the patch.
