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:
