Buckling Analysis of Composite Truncated Conical Shells Under Mechanical Loading in Thermal Environments
In this paper a finite element method for investigating of thermo-mechanical buckling behavior of composite
truncated conical shells is presented. In this study it is assumed that the conical shells subjected to mechanical and thermal
loading simultaneously. Displacement field is based on the first shear deformation theory (FSDT). Using the principle of
minimum total potential energy, stiffness matrix and geometric stiffness matrix are derived. With solving Eigen-value
problem stability region identified. After validating the results of developed FE code with those available in the literature, the
effect of fiber angles, thickness to radius ratio and semi vertex angle on thermo-mechanical buckling behavior of truncated
conical shells is studied.
