Abstract
A class of singular potential problems using the boundary element algorithm with singular shape functions is investigated. In the proposed algorithm, an additional constraint equation is introduced in the global system making the stress intensity factor a degree of freedom. This constraint relates the stress intensity factor to the nodal variables solved by BEM. The numerical results for a model problem (Motz I) show that the proposed algorithm is very effective even on coarse meshes.
