100Smeared Stiffener IdealisationIf there are many closely spaced stiffeners then it can be assumed that their effect is distributed over the skin between the corner points. In this case, the effect of the stiffeners can be smeared over the skin and the effective thickness of the skin modified to allow for them. However, the stiffeners only carry direct stress, they do not carry any significant shear stress. This means that the idealised skin will now have two different thicknesses.
