Thermoelastic Theory of Cylindrical Sandwich Shells with Piezoelectric Sensors or Actuators

Document Type: Proceeding Paper

Part of: Engineering, Construction, and Operations in Space IV


Cylindrical sandwich shells with piezoelectric longitudinal and ring elements bonded to the outer and inner surfaces are considered in this paper. Thermal effects are included in the analysis, although the influence of temperature on mechanical and piezoelectric properties is disregarded. Governing equations of motion and the boundary conditions derived in the paper can be applied to the shells with piezoelectric sensors or actuators or to the shells with a feedback control including both sensors and actuators.
