Thermo-electro-mechanical buckling analysis of cylindrical nanoshell on the basis of modified couple stress theory

  • Fahimeh Mehralian
  • Yaghoub Tadi Beni


In the present study, the buckling of piezoelectric cylindrical nanoshell subjected to an axial compression, an applied voltage and uniform temperature change resting on Winkler-Pasternak foundation is studied analytically. The modified couple stress theory combined with the geometrical nonlinear shell model is employed to derive the equilibrium equations and boundary conditions. The numerical results are proposed for the buckling of simply supported cylindrical nanoshell using the Navier-type solution. Thus, the effects of different parameters such as dimensionless length scale parameter, length and thickness to radius ratio, temperature change, external electric voltage and Winkler and Pasternak foundation stiffness on critical buckling load are illustrated. It is shown that increase in dimensionless length scale parameter results in increasing critical buckling load and even intensifying the influence of other parameters, such as length and thickness, on critical buckling load.
