Calculation on High Stress Concentration Field of Elliptical Hole Problems by the MFS Using Dissimilar Allocation of Source Loads

Abstract:

It is well known that the MFS based on the collocation method can be implemented easily and gives good accuracy in most cases[1,2,3]. The stability of the accuracy, however, depends on the source location. Recently, Karageorghis et.al. calculated SIF of a central crack in a rectangle plate using a similar shape of uniformly distributed points[4]. Gorzelanczyk et.al. made some remarks concerning the shape of the source contour with application of the MFS to elastic torsion of prismic rods. It is reported that the accuracy is better when the source contour is geometrically similar to the boundary of the region in comparison to the source contour with a shape of a circle[5].
