Abstract : A method of analysis for computing deformations and stresses in a clamped-free circular cylindrical shell under the action of nonaxisymmetric loads and temperatures is given. The analysis, which is based upon the Rayleigh-Ritz Method and the principle of the stationary value of the total potential, is suitable for a shell with a longitudinally varying wall thickness and elastic modulus. The computation was programmed for routine solution on the IBM 7090 or 7094 digital computers. Total machine time for a single loading case is 0.6 minutes on the 7094 machine. The results of an experimental study of a clamped-free cylinder under a concentrated radial force are given and are compared with theoretical predictions. The theoretical and experimental deflection results are found to be in excellent agreement for the case where the force is near the free end but the theory seriously underestimates the deflections if the concentrated force is applied in the vicinity of the clamped end. Although it was not verified, based upon the results of the concentrated loading, it is believed that the accuracy of the method for smoothly varying distributed loads should be very good. (Author)
