Abstract
It has been problematic to develop simple and practical automatic mesh generation techniques that can minimize the amount of required input data and can generate a lot of nodes. In particular for the application of automatic mesh generation to stress concentration area simple computer algorithms for managing input and output data are necessitated. In order to satisfy these requirements the Fuzzy reasoning is chosen here as an automatic mesh generation scheme which is applicable to the triangular element. The application target of this method is to accurately evaluate the stress concentration factor of the plate with hole. The element refinement algorithm are used here to optimize meshes based on the element shape and to smooth strees obtained from the Fuzzy reasoning.
