In this paper the evaluation of Leak-Before-Break for pates with a surface crack has been carried out by the Line Spring Method. The COA criterion is used for the crack growth analysis and the load-displacement curves of surface cracked plates under tension are obtained for various crack geometries. The load-displacement curves are classified into two types. One shows the crack penetration after the maximum load, and another shows the crack penetration before the maximum load. Under the load controlled system, the latter satisfies Leak-Before-Break while the former does not. Next, the effect of the initial geometry of surface cracks to Lead-Before-Break is shown by LBB diagram. The tearing in stability and Leak-Before-Break of surface cracked plates can be evaluated by this diagram.
