The cylindrical shell is a widely used structure in engineering practice, and its main form of failure instability due to buckling. As classical problem the field mechanics, stability shells has been studied extensively. However, large difference between theoretically predicted results critical buckling load experimental for subjected uniform axial pressure contributed continuous development th...

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 ...

In this study, the structural reliability of plate-stiffened prismatic pressure vessels was analyzed over time. A analysis performed using a time-dependent method based on response surface (RSM). The vessel had rectangular cross-section with repeated internal load-bearing structures. For analysis, structure modeled as strip, and to identify changes in index when general corrosion pitting occurr...

Acoustic radiation through a system of double-walled shells, lined with porous foams, and stiffened by annular plates simultaneously is studied. Based on modeling, the foams as absorbent fluid property, acoustic characteristics structure are presented for various sandwich construction means vibro-acoustic finite element method automatic matching layer technology. It noted that equipping enhance...

An analytical investigation is conducted to predict the post-buckling strength of laminated composite stiffened panels under compressive loads. When a stiffened composite panel buckles, the skin would deform into a sinusoidal mode shape, and hence induces additional moments and forces near the skin-stiffener interface region. These induced loads would cause the existing small edge delamination ...
