A new BEM algorithm is proposed in the paper.
This algorithm is based
on the coincident collocation of the non-singular boundary integral equa-
tions(BIEs) of displacement and its derivatives, and the basic variables of
the new BEM system equation are the boundary nodal displacements, trac-
tions and displacement derivatives.
Due to the non-singular character of
the BIEs, all integrals in the algorithm can be evaluated by the Gaussian
Furthermore, as the displacement derivative can be considered
independent to the displacement in the formulations, the conforming ele-
ment can be used for this algorithm.
Once the new BEM system equation is
solved, the boundary stress can be evaluated immediately from the obtained
