An Investigation of the Fatigue and Fracture Properties of Selected Hull Plate Samples from the Coast Guard Cutter Staten Island.
The fracture toughness, fatigue crack propagation behavior, and tensile properties were evaluated for six selected hull plate samples at the icebreaker operating temperatures of +28F and -30F. In addition, the nil-ductility transition temperature, chemical composition, average grain size and suscept...
