摘要：
This paper presents a new regularized integral representation of the stress tensor at internal points. Numerical implementation is given for both the non-regularized and regularized integral representations of internal stresses as well as for the expression of boundary stresses. The complete stress tensor at any internal and boundary points is expressed in terms of the nodal values of boundary displacements and tractions. Emphasis is given to comparison of accuracy of numerical computation of stresses by regularized and non-regularized integral representations.
