Abstract: Abstract-Thin cylindrical shells are most widely used structural forms in aerospace and missile applications.in designing efficient and optimized shell structures they become increasingly sensitive to buckling. The catastrophic nature of buckling failure often brings surprises in testing by failure at staggeringly low loads as compared to theoretical predictions.it is well known that the experimental disparity is mainly attributed to geometrical imperfections like damage in the structure.in missile airframe the cylindrical shell structures are generally provided with cutouts for accessing internal components during integration. The cutouts invariably reduce the strength of the thin cylindrical shell more specifically the buckling load.to improve strength stiffeners provided around the cutout. Due to this reduces buckling load. This study is aimed at generating elaborate data on buckling load with different cutout sizes and the strengthening effect by providing stiffener around the cutout. With efficient general purpose FEA packages, for the parametric study of the problems of this nature is relatively inexpensive.
Keywords: cylindrical shells, cutouts, stiffener, buckling, ANSYS.
