STRESS INTENSITY FACTORS FOR CORNER CRACKS AT HOLE UNDER REMOTE TENSION

The three dimensional weight function method developed in 4,5 is used to determine stress intensity factors for corner cracks at a hole in finite thickness plates subjected to remote tensile loading. The geometry parameters considered are r/t=0.5,l,2;a/c = 0.2,0.5,1,2;a/t= 0.2,0.5 within c/r≤2.The results are compared where possible, with other solutions available in the literature. Generally good agreement is observed. The effect of two dimensional unflawed stress distribution on the weight function resu...
