Paper Abstract

An elasticity 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 non-uniform distributions of the piezoelectric effect are studied and results are verified using a finite element analysis based on axisymmetric 2-D 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.
