【 摘 要 】

In the present article, the influences of interlaminar bonding imperfection and constant magnetic field, as well as hygrothermal environmental conditions, on the stresses and displacements of a cylindrical shell with surface bounded sensor and actuator are investigated. The multiphysics analysis was carried out to explore the effects of moisture, temperature, electrical and mechanical loadings as well as magnetic field. The shell was simply supported and could be rested on an elastic foundation. The material properties of the shell and piezoelectric sensor and actuator were assumed to be functionally graded in the radial direction according to power-law function. Using the Fourier  series expansion method through the longitudinal direction and the differential quadrature method (DQM) across the radial direction, governing differential equations were solved. The validity of the present work was verified by comparisons with other published works. Numerical results are presented to illuminate the effects of aspect ratio of shell and magnetic field on the responses of the hybrid shell.
