Analysis of Composite Cylindrical Shell With And Without Cutout Section

The objective of this study is to analyse the composite cylindrical shell with and without cutout by applying axial load on Aramid fiber reinforced polymer (AFRP) and Basalt fiber reinforced polymer (BFRP) shell. The Static and Eigen value buckling analysis is done on shell model. The circular, elliptical and rectangle cutouts are considered on cylindrical shell. The compressive stress, deformation, buckling load of each case for cylindrical shell is obtained from ANSYS software. As Fiber reinforced composite materials are more efficient and reliable structures because of their high strength and specific modulus compared to other metallic materials. Stress increases for shell with cutout when compared to the shell without a cutout. The responses of composite shells with cutouts are obtained using geometrically nonlinear FEM software, carried by ANSYS. Composite cylindrical shells are often subjected to defects and damage from both in-service and manufacturing events. Finite element models are also used by many researchers to characterize the behaviour of cylindrical shell considering different types of material and geometrical imperfections. The buckling load value is maximum in circular cutout and minimum in the without cutout. Different changes in the material properties are used here to analyse the static and buckling behaviour of composite shells.
