The skin takes pressure loads via inplane stretching and shear loads. It also takes compression loads up to buckling. Beyond buckling, extra care must be exercised to account for the skin deformations and additional failure modes, not examined so far, such as the skin—stiffener separation, which is discussed in this chapter. The stiffeners take bending and compression loads. It is readily apparent that the robustness and efficiency of a design will strongly depend on how one can ‘sequence’ the various failure modes so benign failures occur first and load is shared by the rest of the structure, and how one can eliminate certain failure modes without unduly increasing the weight of the entire panel. This chapter examines some aspects that manifest themselves at the component level, with both skin and stiffeners. This includes modelling aspects such as smearing of stiffness properties and additional failure modes such as the skin—stiffener separation.
