Thermal Buckling Characteristics of Composite Conical Shell Structures

Abstract

Thermal buckling and free vibration analyses of multi-laered composite conical shells based on a layerwise displacement theory are performed. The Donnells displacement-strain relationships of conical shell structure are applied. The natural frequencies are compared with the ones existing in the previous literature for laminated conical shells with several cone semi-vertex angles. Moreover, the thermal buckling behaviors of the laminated conical shell are investigated to consider the effect of the semi-vertex angle, subtended angle, and radius to thickness ratio on the structural stability.
