These stress functions can be reduced to solve various types of hole boundary problems such as circular hole, elliptical hole, square hole and crack. The stress fields near the rounded corners of rectangular hole for different angular position of loading are determined. The variation of stress concentration factor with normalized corner radius for various loading oases are obtained and compared with the existing results.</span>
