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.
