Elastic Stability and Buckling

Chapter 7 covers the topics of elastic instability and buckling of columns and plates. Various examples of the column configurations are illustrated for better understanding of the solutions. This chapter covers the topics of elastic instability and buckling of columns and plates. Radius of gyration is defined as the square root of the column second moment of area over the cross-sectional area of the column. Likewise, a plate is called "thin" plate when its thickness is at least one order of magnitude smaller than the span or diameter of the plate. For a simply supported column of 10 ft. long with square cross-section of 2 in. by 2 in., determine the critical buckling stress. Assume an aluminum 6061-T6 column material. For a simply supported plate of 40 in. long and 13 in. wide, with thickness of 0.05 in., determine the critical buckling stress. Assume annealed steel plate material.
