| Abstract: |
| In order to solve the buckling problem of functionally graded carbon nanotube reinforced composite (FG-CNTRC) plates with carbon nanotubes (CNTs) orientation angle resting on an elastic foundation,a meshless analysis model based on improved Reddy’s third-order shear deformation theory (TSDT) and moving least square (MLS) is proposed.This model avoids the difficulty of imposing the second kind of boundary condition in the meshless method,and can satisfy the free surface conditions of medium thick/thick plates without introducing additional shear correction factors.Based on the principle of minimum potential energy,the governing meshless equations for the buckling of FG-CNTRC plates on an elastic foundation are derived.The convergence and effectiveness of this method are verified by a benchmark example.The effects of the orientation angle,volume fraction,distribution pattern,foundation coefficient,width-to-thickness ratio and boundary condition on the critical buckling loads of FG-CNTRC plates are analysed. |
