The quarter elliptical corner crack represents the induced FIB defect assuming that the defect depth is , and the defect length is c , knowing that < . The following formula was introduced as the stress intensity factor solution for the specified geometry in Fig. A .1 as: K I = � σ √ where the variable Q can be calculated making use of the equation: Q = 1+1.464( c ) 1 . 65 And the variable F is computed using the set of formulas as follows : F = [ 1 + 2 ( ) 2 + 3 ( ) 4 ] 1 2 Ø 1 = 1.08 − 0.03 � � 2 = − 0.44 + 0. 1 3 .0 + 6
