A two dimensional stress analysis of finite plate or strip containing eccentric cracks was conducted by using a complex stress function of series form which satisfies explicitly the traction-free condition along the crack edge. The unknown coefficients involved in the assumed stress function were determined by the modified boundary collocation method based on the resultant forces or average displacements along the boundary segments. In order to obtain those coefficients, both the direct method and the least square method were examined. Once the stress function is determined, stress intensity factors are obtained by a limiting procedure. The effectiveness of the numerical values obtained were examined by varying the number of boundary segments and monitoring the stress distribution along those boundaries. Calculated results are presented in tables and figures in the form of correction factors, which involve the effects of loading methods and geometry of the plate to stress intensity factors. The following geometries were treated in the present paper; (1)a rectangular plate with an eccentric crack under uniform tension. (2)a rectangular plate with a pair of collinear cracks under uniform tension. (3)a strip with parallel eccentric cracks under tension. (4)a strip with collinear cracks, whose distance varied periodically, under uniform stress applied on its sides. |
