영문 초록

High Tensile Steel enables to reduce the plate thickness comparing to the case when Mild Steel is used. From the economical view points, this is very preferable, since the reduction in the hull weight. However, to use the High Tensile Steel effectively, the plate thickness may become thin so that the occurrence of buckling is inevitable and design allowing plate buckling may be necessary. If the inplane stiffness of the plating decreases due to buckling, the flexural rigidity of the cross section of a ship's hull also decreases. This may lead to excessive deflection of the hull girder under longitudinal bending. In these cases a precise estimation of plate's behavior after buckling is necessary, and nonlinear analysis of isolated and stiffened plates is required for structural system analysis. In this connection, this paper discusses nonlinear behaviour of thin plate under thrust. Based on the analytical method, elastic large deflection analysis of isolated plate is perform and simple expression are derived to evaluate the inplane rigidity of plates subjected to uniaxial compression.
