COMPUTATION OF BOUNDARY STRESSES BY SOLVING NONSINGULAR BOUNDARY INTEGRAL-EQUATIONS

This paper concerns the derivation of the nonsingular ordinary boundary integral equations for the tangential derivatives of boundary displacements. Having solved these equations after computation of tractions on the boundary, one can evaluate the stress tensor components at any boundary point. The present formulation can be implemented numerically using standard C0-continuous boundary elements for all the boundary densities. The number of integral equations which are to be solved is decreased as compared with the other formulations. Moreover, the formulation is presented in the most general form applicable to two- and three-dimensional problems.
