Hi, a buckling problem can be solved using classic Euler beam theory, where the bending moment of a cross section and deformation in the lateral direction follows a second order different equation. M = -Py = EIy''By solving this equation and apply the boundary conditions, one can obtain the critical load for a simply supported column at two ends:P_cr = EI*pi^2/L^2,where E is the Young's modulus, I is the moment of inertia of the cross section and L is the column length.
