Buckling in aircraft structures

WebJul 12, 2011 · Aircraft Structures concisely and comprehensively presents the basics of aircraft design and analysis and is intended for students in aerospace and mechanical engineering. In three sections and focusing particularly on the function of aircraft parts, this volume treats the fundamentals of aircraft design, excluding the engine and the avionics. In structural engineering, buckling is the sudden change in shape (deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear. If a structure is subjected to a gradually increasing load, when the load reaches a critical level, a member may suddenly change shape and the structure and component is said to hav…
