Buckling in civil engineering
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 … See more Columns The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ). … See more Bicycle wheels A conventional bicycle wheel consists of a thin rim kept under high compressive stress by the (roughly normal) inward pull of a large number of spokes. It can be considered as a loaded column that has been bent into a … See more • Timoshenko, S. P.; Gere, J. M. (1961). Theory of Elastic Stability (2nd ed.). McGraw-Hill. • Nenezich, M. (2004).
