Distribution Of Stresses

An elastoplastic and geometrically nonlinear analysis of two of Ross's swedge-stiffened pressure hulls subjected to hydrostatic pressure loading is presented. Three commonly used swedge forms—trapezoidal, triangular, and sinusoidal-shaped—are considered. Comparisons on the responses of these three swedge-stiffened shapes are included. The load/displacement relations as well as the distribution of stresses with plastic zone spread phenomena are also illustrated.
