A steel plate with a 0.4 mm long (i.e. '2a') internal crack is subjected to a stress of 700 MPa. What is the stress intensity factor in MPa mo5? Predict whether the steel plate will fracture or not. Consider the fracture toughness of steel as 50 MPa m0.5 78.5, so fracture occurs. 55.5, so fracture occurs. 35.5, so fracture does not occur. 48.5, so fracture does not occur.
