It has been found that load state plays an important role in crack growth rates in fibre/metal laminates. It is expected that material anisotropy is a major cause, and that residual strength of reinforced panels may be affected. Accordingly, an extension of the displacement compatibility method of damage tolerance analysis is presented. The present work accounts for material anisotropy and panel load condition. Comparisons with finite element results show that the extended displacement compatibility method gives accurate stress intensity results for anisotropic panels under tension and under shear loading. The stress intensities obtained using the displacement compatibility method have been used in conjunction with material R-curves to calculate residual strength curves of stiffened panels.
