Abstract : The maximum stresses in a spherical shell are obtained which is lifted or towed by a cable or any mechanical power hoist. In view of the highly localized nature of the maximum stress induced in a spherical shell due to local loading, the nonlinear (large deflection) shallow shell theory is adopted for the analysis. A nonlinear relaxation technique in conjection with finite difference approximations is introduced for the numerical integration. Results obtained here are presented in the graphic form which may be readily used by engineers in practical design. (Author)
