A method of stiffening the integral ribs of a panel to prevent crippling of the ribs during forming of the panel. The method provides that anti-crippling stiffeners are attached to the ribs, such as by using clamps. Then, the panel is formed while the anti-crippling stiffeners are attached to the ribs. The anti-crippling stiffeners add stiffness to the ribs and prevent the ribs from crippling during forming of the panel. The anti-crippling stiffeners could be C-shaped and be attached to the panel using C-shaped clamps. Both the panel and the anti-crippling stiffeners could be formed of aluminum. Another embodiment involves clamping at least one anti-crippling strap to the flange of a wing stringer to prevent the flange from crippling during forming of the wing stringer.
