【 摘 要 】

Using  principle  of  minimum  total  potential  energy  approach  inconjunction  with  Rayleigh-Ritz  method,  the  electro-thermo- mechanical  axial  buckling  behavior  of  piezoelectric  polymericcylindrical  shell  reinforced  with  double-walled  boron-nitridenanotube  (DWBNNT)  is  investigated. Coupling  between  electricaland mechanical  fields  are  considered  according  to  a  representativevolume  element  (RVE)-based  micromechanical  model.  This  studyindicates how buckling resistance of composite cylindrical shell mayvary  by  applying  thermal  and  electrical  loads.  Also,  applying  thereverse voltage or decreasing  the  temperature,  increases  the criticalaxial buckling  load. This work showed that the piezoelectric BNNTenhances  on  the  whole  the  buckling  resistance  of  the  compositecylindrical shell.
