Mechanical response of laminated composite cylindrical shell subjected to radial patch loading

Abstract

Due to significant amount of applications in industries, composite materials and structures are subjected to many different types of loading. One of the most common types of these loading is radial patch loading. Due to the complexity, calculation of radial shell deflection is the main character of the cylinder behavior when subjected to patch loading. The aim of this study is to investigate the mechanical behavior of composite cylindrical shell subjected to radial patch loading. The radial deflection of the laminated shell is investigated in detail where analytical and finite element methods (FEM) are used. The results through both approaches are compared to validate the accuracy of the analytical method. This is followed by a parametric study to determine the effect of some operation parameters on radial displacement. The results show close agreement between the analytical and numerical methods.
