Fracture mechanics
Q.5 a) Determine the critical crack size and critical load in a center-crack. A steel bar 50 mm wide and 8 mm thick with center crack of 10 mm long is loaded to a tension stress 120MPa. In Mode I failure crack stable, if fracture toughness Kc = 60MPam-2. Use the correction factor, a = f (a / w), for this crack ) = configuration -tan ta
