Some Remarks on Finite Element Mesh Modeling of Crack-Tip Area

The aim of this paper is to present some remarks on the arrangement of finte element mesh modeling of the area adjacent to the crack-tip which locates in two-dimensional area. Since the stress distribution near crack-tip is singular, the arrangement of mesh pattern and the selection of mesh type in the crack area govern the accuracy of the solution. This paper gives some informations on the arrangement of finite elements in the area which are obtained through numerous number of numerical experiments. And the effectivity of Zooming Technique for stress analysis is clarified through the experiments.
