Abstract:

The numerical results of the solution of the interaction problem of a hydrostatically loaded, infinitely long circular cylindrical shell, reinforced by equally spaced stepwise discontinuous rings, with two uniform halves but different mean radii and cross sectional properties, indicate a high bending stress concentration at the discontinuity. The method of solution is limited by the magnitude of the eccentricity and area ratios. That is, convergence of the interaction load expressed as a Fourier series is very slow if these quantities are high. Because of the complex nature of the problem, six approximate analyses have been studied. These approximations yield results which, when compared with the more complete analysis, are reasonable and useful. Author
