Buckling is a mathematical instability, leading to a failure mode when a structural member is subjected to high compressive stresses. Control of buckling with minimum weight addition is an important requirement in space structures. The main objective of buckling control is in controlling the critical modes and hence improving the load carrying capacity of the structure. While several scholarly books exist on the application of piezoelectric materials for vibration control, books on buckling control of structures seldom exist. This book provides a good introduction to the basic theory of the technique and its common applications especially to column and cylindrical shell structures. The book emphasizes on the feasibility of buckling control of column and shell structures with the help of numerical and experimental analyses.
