The buckling deformation can be arbitrarily chosen to be symmetric about θ= θ = 0 and will then be antisymmetric about θ=π/2k θ = π / 2 k . For this case we know the lowest buckling mode ( k= k = 2) has the smallest critical load, so a mesh of 45° extent should suffice for eigenvalue buckling estimation.
