In this paper, the buckling analysis of thin walled composite cylindrical shells with and without cutouts is investigated by applying axial load on Glass Fiber Reinforced Plastic (GFRP) shell. The effect of cutout not only introduces stress concentration but also significantly reduces the buckling strength. The column is fixed at one end and load is applied at the other end. The Static and Eigenvalue buckling analysis is done on shell model. The circular, elliptical and rectangle cutouts are considered on cylindrical shell. The buckling analysis is repeated in each case. The compressive stress, buckling load factor and lateral strain of each case for cylindrical shell is obtained from ANSYS software. The buckling load decreases for shell with cutout when compared to the value of the shell without a cutout. Stress and lateral strain increases for shell with cutout when compared to the shell without a cutout. The buckling load value is maximum in circular cutout and minimum in the rectangular cutout.
