Thermal postbuckling behavior of laminated composite spherical shell panel using NFEM

摘要: Postbuckling behavior of laminated shell panel in thermal environment is reported this article. The geometric nonlinearity introduced Green–Lagrange sense and the model developed for geometrically large translations and/or rotations excess deformation curved based on higher order shear theory (HSDT) using nonlinear finite element. governing equation derived by minimizing energy expression. postbuckling strength terms temperature ratio (postbuckling to buckling temperature) obtained a direct iterative method. results are compared with those available published literature. Some new computed different parameters such as layup sequences, thickness ratios, amplitude boundary conditions, aspect various curvature ratios presented.
