A NOVEL METHOD OF STRESS-ANALYSIS OF AN INFINITE-PLATE WITH ROUNDED CORNERS OF A RECTANGULAR HOLE UNDER UNIFORM EDGE LOADING

In this paper, a new method is presented which uses Schwarz Alternatin g technique to determine the two complex stress functions for the stre ss field in two dimensional isotropic homogeneous infinite plate with reactangular hole subjected to uniform uniaxial, biaxial, and shear ed ge loadings. These stress functions can be reduced to solve various ty pes of hole boundary problems such as circular hole, elliptical hole, square hole and crack. The stress field near the rounded corners of re ctangular hole for different angular position of loading are determine d. The variation of stress concentration factor with normalized corner radius for various loading eases are obtained and compared with the e xisting results.
