摘要：
Results of both analytical and experimental investigations of dynamic behavior cylinder with rectangular cutout; potential and kinetic energy of thin shell are approximated by two-dimensional finite difference methods; algebraic eigenvalue problem is obtained by application of principle of minimum total energy; resulting algebraic equation system is solved on high-speed digital computer; analytical study shows influence of cutout on natural frequencies of shell, on mode shape, and on internal stress distribution cutouts range in size from very small holes to openings having included angle of 120//0.
