SOLUTION OF STRESS INTENSITY FACTORS BY WEIGHT FUNCTION FOR SMALL CORNER CRACKS IN PLATES

The three-dimensional weight function method developed in 2,3 is usedto determine stress intensity factors for small corner cracks in plates subjected to remote tension and bending. The geometry parameters considered are c/b=0.1;a/c = 0.2,0.4,0.6, l,2;a/t = 0.01,0.05,0.1 and 0.2, which cover the range of small surface crack problems commonly encountered in fatigue and fracture studies and applications. The results are compared with the finite element solutions in 1 . Very good agreement is observed. The...
