This paper presents both experimental and analytical investigations concerned with the dynamic behavior of seamless cylindrical shells with two rectangular cutouts. These cutouts are located opposite to each other in the circumferential direction and their circumferential or axial lengths are systematically varied. The experimental results of free-clamped cylindrical shells made of epoxy resin agreed with the analytical ones obtained by use of finite element method. The variation of the circumferential length of rectangular cutouts has a greater influence on the dynamic behavior of cylindrical shells compared with that of the axial length.
