Two collinear Griffith cracks subjected to uniform tension in infinitely long strip

The problem of determining the stress field in an elastic strip of finite width when the uniform tension is applied to the faces of two collinear symmetrical cracks situated within it is considered. By using the Fourier transform, the problem can be solved with a set of triple integral equations. These equations are solved using Schmidts method. This method is suitable for solving the strips problem of arbitrary width.
