Abstract

By extending Bückner’s superposition principle and alternating iteration method, this presentation studies the dual holes interactions. A newly developed numerical scheme is embedded in the conventional Gauss-Legendre quadrature routine for evaluating the boundary integral holding stress singularities. This developed scheme can avoid numerical singularity and facilitate the achieved stress field to be exact as that of analytical solution; however the chosen Gaussian integration points must enter a large quantity. This presentation uses an infinite plate with a centered hole strained by remote axial loading as a testing example, and the numerical results are capable of reaching the analytical solution in the evaluation. The accurate stress estimation in the stress field of the dual holes interacting can therefore locate the dual holes in a very close proximity and no divergence will occur during evaluating the interacting stress concentration between holes.
