Numerical Investigation Of Stiffened Composite Cylindrical Shell Subjected To External Pressure
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 ...
متن کاملTheoretical and Experimental Collapse Analysis of Ring Stiffened Shells Using Finite Element Software Packages and Application of Results to a Submarine Pressure Hull
It is empirically established that, due to a number of factors involved, a classical (linear) analysis of buckling pressure is impossible. Nonlinear theories of buckling are, therefore, required that involve effective factors such as imperfections and welding effects. In this study, models are developed which are as close to allowable standard deviations as possible. In the next stage, their bu...
متن کاملComputer aided reliability based design of ring-stiffened cylindrical shells under external pressure
A Level I code format is proposed for the buckling design of ring-stiffened cylindrical shells under external pressure. Depth independent partial safety factors to be applied to the resistance (collapse pressures), are proposed for the four relevant collapse modes Unterframe Shell Collapse, Frame Yield, Plate Yield and Frame Tripping), covering design and fabrication factors. A partial safety f...

متن کاملFinite Element Analysis of Buckling of Thin Cylindrical Shell Subjected to Uniform External Pressure
One of the common failure modes of thin cylindrical shell subjected external pressure is buckling. The buckling pressure of these shell structures are dominantly affected by the geometrical imperfections present in the cylindrical shell which are very difficult to alleviate during manufacturing process. In this work, only three types of geometrical imperfection patterns are considered namely (a...
