Abstract

Elastic Mode 1 and 2 stress intensity factors for stiffened, cracked plates were calculated for panels loaded both in tension and shear by the finite element method. The influence of stringer thickness, rivet spacing and stringer stress intensity factors and stringer stresses were analyzed. The influence of plastic deformation was studied for the case of tensile loading. The J-integral values and stringer stresses were calculated. Contrary to the elastic case, the stiffeners failed to provide much protection for the panels and did provide crack arrest.
