                            Figure 4.12  Plate Buckling

                For a transversely stiffened plate with an aspect ratio of a < 1, as shown in Figure 4.12, the
                critical stress will correspond to n=l,  which leads to a more convenient expression for the
                elastic compressive buckling stress:

                Figure 4.13 shows a longitudinal stiffened plate, for which k, is approximately 4 so that the
                elastic critical stress is given by:
