摘要：
In this paper a study of a Superplastic Formed/Diffusion Bonded (SPF/DB) aircraft wing under working load is presented. The damaged structure is considered and the stress intensity factors are evaluated for cracks of different sizes and in different positions. The aim of this work is to demonstrate the effectiveness of the boundary element method to investigate the behaviour of cracks in damaged structures.
