The paper deals with the interaction between three coplanar Griffith cracks located symmetrically in the mid plane of an orthotropic elastic layer of finite thickness 2h sandwiched between two identical orthotropic half planes. The Fourier Transform Technique is used to reduce the elastostatic problem to the solution of a set of integral equations which have been solved by using the finite Hilbert transform technique and Cook's result. The analytical expressions for the stress intensity factors and stress magnification factors at the crack tips are obtained for large h. Numerical results for stress intensity factors and stress magnification factors have been illustrated graphically.
