| Abstract: | In this paper, a class of welding problem with interracial crack is studied by the method of complex variable and the theory of boundary value problems of analytic functions. Using proper decomposition of the functions and integral transformation, the problem is reduced to a singular integral equation, whose solution is given by the theory of integral equation. The stress distribution of elastic body is obtained in a closed form. The general expressions of stress intensity factors are also derived. |
