چکیده

Abstract— The present study is devoted for the development of a mathematical model to predict the structural behavior and critical pressure of composite cylindrical shell under external pressure using finite element analysis. The composites can be tailored to match the external loading. The effect of fibre orientation angle along with stacking sequence of the composites on the loading carrying capacity of the structure is assessed. A quantitative assessment of the effects of discrete stiffeners on the local and global behaviour of shells stiffened by rings is carried out for understanding the response of structure. The study captures the local effects of the stiffener spacing and highlights the effect of eccentricity of stiffeners on the strength of shells. The response of the composite shells has been investigated for different values of the shell thickness.
