Thin plates subjected to uniformly varying edge-displacements

摘要

This paper is concerned with plates subjected to linearly varying load. Energy method based on effective width concept is applied to study the post buckling behaviour of plates with initial imperfection and clamped along loaded edges and simply supported on unloaded edges. Expressions for effective width are obtained for two cases in which the unloaded edges may be held straight or allowed free to pull-in. Results are given to illustrate the variation of effective width.
