Transcribed Image Text:

P r A pipe with a mean radius of r = 600 mm and a wall thickness of t = 18 mm is designed to operate under internal pressure, p. It is made of a steel with a fracture toughness of KIC = 110 MPa m. At inspection, an edge crack on the surface of the pipe with a length a = 9 mm was detected (see figure). What is the maximum internal pressure, p, that the pipe can carry that does not cause brittle fracture? (You may ignore the curvature effects on the stress distributions and the geometry factor.) Give your answer in MPa to 3 significant figures.
