Long Brittle Crack Arrest Behavior in Fillet Tee Joint of Large Container Ship
ABSTRACT Long brittle crack arrestability is extremely important in welded joints of heavy gauge steel plates used in large container ships. Recently, much attention has been focused on potential long crack propagation along welds using large heat input. This paper examines the application of a fillet Tee joint to the strength deck structure of container ships to enhance crack arrestability. The ultra-large scale crack propagation tests were conducted to investigate long brittle crack propagation/arrest behavior in fillet Tee joint structures. These test results showed that the long brittle cracks which rush into the strength deck and hatch side coaming could arrest in the weld metal of fillet Tee joint structure under the specific conditions controlling the leg length and toughness of the fillet weld metal. This phenomenon shows the advantage of using a fillet Tee joint for long brittle crack arrest in the strength deck structures of large container ships.
