Abstract
An elastoplastic and geometrically nonlinear analysis of two of Ross's swedge-stiffened pressure hulls subjected to hydrostatic pressure loa ding is presented. Three commonly used swedge forms-trapezoidal, trian gular, and sinusoidal-shaped-are considered. Comparisons on the respon ses of these three swedge-stiffened shapes are included. The load/disp lacement relations as well as the distribution of stresses with plasti c zone spread phenomena are also illustrated.
