Figure 12 : Effect of crack inclination angle α on K I for two parallel cracks; a/W = 0.08, k = 0.75, S = 1.5 and B = 24 mm. C ONCLUSIONS ffects of crack inclination angle on stress intensity factors for two parallel and non parallel cracks are analysed and found to have significant effect on lower and upper crack. The stress intensity factors for non parallel cracks have similar value for upper and lower cracks, whereas in case of parallel cracks the value of stress intensity factor is E
