Stress analysis of bonded joints by boundary element method

Document Type


Publication Date



Boundary element method (BEM) has proven to have very good resolution of large stress gradients such as in front of cracks and in regions of stress concentration, yet its application in analysis of bonded joints is practically non-existent even though large stress gradients exist in the bonded region and bonded joints are one of the critical technology in modern design. This is because application of BEM to bonded joints is not simple or straight forward. This chapter describes the commonality and differences between BEM and other approximate methods, advantages of BEM application to bonded joints, the research challenges, BEM formulation, the discretization process and the sources of errors, the mesh refinement techniques, and some numerical results. © 2008 Springer Berlin Heidelberg.
