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.
