Effect of boundary conditions on thermal buckling of laminated composite shallow shell

Abstract

Levy type method is implemented for investigating the behavior of thermal buckling load of the symmetric and anti-symmetric cross-ply and angle-ply laminated spherical shallow shell subjected to uniform temperature distribution based on first-order shear deformation theory. Some design parameters will be considered for cross-ply and angle-ply to demonstrate the parametric effects such as material types, modulus ratio, aspect ratio, shallowness ratio, length to thickness ratio and lamination schemes and the governing equations are solved with a computer code established in MATLAB environment to get the required. Also, the verification of present levy type results is checked by comparing the extracted results with previous studies. The extracted results show that the thermal buckling load increase with increasing in modulus ratio, while decrease with increasing in aspect ratio, shallowness ratio and length to thickness ratio.
