Abstract: In this paper, the problem of an infinite plane with a circular hole welded by a nearly circular plate with a crack of different material is considered. The problem is transformed into solving a certain boundary value problem of analytic functions and then reduced to solving a singular integral equation along the crack. The formulas and some numerical results of the factors of stress intensity for the cases Mode I and Mode II are obtained at the end of this paper.

Key words: traffic flow, dynamics model, kinematic wave property
