WebBuckling of Columns. Leonhard Euler a famed swiss mathematician developed the Euler theory of column buckling in 1742. Column buckling is a type of deformation caused by … WebFor the first mode of buckling (n = 1): 1 sin x yC L π = As shown of the previous page, the column buckles into a sine wave and the constant C 1 represents the maximum deflection of the midpoint of the column. The value of C 1 is indeterminate and can be obtained from a nonlinear analysis. This is typically of little
