Abstract This paper develops a new numerical framework for mode III crack problems of thin-walled structures by
integrating multiple advanced techniques in the boundary element literature. The details of special crack-tip
elements for displacement and stress are derived. An exponential transformation technique is introduced to
accurately calculate the nearly singular integral, which is the key task of the boundary element simulation of
thin-walled structures. Three numerical experiments with different types of cracks are provided to verify the
performance of the present numerical framework. Numerical results demonstrate that the present scheme is valid
for mode III crack problems of thin-walled structures with… More >
