The problem of determining the stress and the displacement fields in the neighbourhood of two Griffith cracks is reduced to the second king of Fredholm integral equation by using Fourier transform. The solution of this integral equation is obtained by expanding the unknown function in terms of (a-1) -a being half of the width of the strip. The partial closure of the crack is also considered. The numerical results for special point body force are show graphically.
