Effect of Different Boundary Conditions and Materials on Smart Composites

In this paper, an analytic solution to the axisymmetric problem of a radially polarized, piezoelectric hollow cylinder was developed. The stresses in multi-layered elasto-piezoelectric composite cylinders in the state of axisymmetric plane strain were obtained. Variation of hoop stresses in the metal layer because of piezoelectric layer were investigated. Finally, the effects of different boundary conditions as well as piezoelectric materials on the stress state of the metal layer were studied.
