STRESS INTENSITY FACTOR OF A CORNER CRACK

The alternating method for elliptical flaw analysis has been extended to solve corner flaw (and surface flaw) problems by prescribing appropriate fictitious pressure on the elliptical crack surface which protrudes into the free space. This procedure accelerates the numerical convergence of the iteration process and extends the applicability of the third order polynimal of pressure distribution. The improved alternating procedure is then used to determine stress intensity factors in corner flaws with aspect ratios of a/b = 0.98, 0.4 and 0.2 and subjected to uniform or linearly varying pressure distributions.
