Large Deflection Behavior of Initially Imperfect Rectangular Plates under Uniform End-Shortening and Extension -- Theoretical and User's Manual.
Abstract
The behavior of plates after buckling is very different from that associated with a simple strut. Thin plates may carry loads many times greater than their initial buckling loads, whereas the critical buckling load for a strut represents its ultimate load-carrying capacity. In this report an energy technique is used to establish the stress distributions and loads associated with the application of uniform end-shortenings to thin rectangular plates. The plates can have an initial imperfection that is assumed to vary in a prescribed manner. Initial imperfections are very common for thin skin-stiffened structural configurations that are typical of most aircraft construction. A description of the theory, its assumptions, and the resulting computer program are presented.
