Large‐Deflection and Ultimate Strength Behavior of Plates
The ultimate strength behavior of a plate under predominantly compressive loads is much more complex involving buckling and plastic collapse than a plate under predominantly axial tensile loads that would fail by gross yielding. This chapter presents the ultimate strength formulations of plates under combined inplane and lateral pressure loads accounting for the effects of initial imperfections in the form of initial deflection and welding residual stresses. It shows the ultimate strength behavior with varying magnitudes of lateral pressure, as obtained by nonlinear finite element method analysis (FEA). The chapter also shows the elastic‐plastic large‐deflection behavior of steel or aluminum plates under longitudinal axial compressive loads with or without initial imperfections until and after the ultimate strength is reached. Due to the bathtub‐type deflection, the rotation and deflection around the plate edges are normally greater than those of the sinusoidal pattern, resulting in larger values of the membrane stresses.
