Analysis of surface stress in the thin bodies by <br /> natural boundary element method<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 1
Abstract
At the evaluation of surface stress in thin bodies by natural boundary element method, the nearly strongly singular integrals occurred in natural boundary integral equations when the boundary source points were close to the opposite contour. A completely analytical integral formula was presented by means of integration by parts. The analytical natural boundary integral equations were developed to evaluate the surface stress cooperated with the conventional displacement boundary integral equations. The results of the numerical investigation demonstrate the present method can analyze the surface stress in much thinner bodies in comparison with the conventional method.
