The solution of the problem of diffraction of obliquely incident longitudinal waves by two equal, parallel, and coplanar Griffith cracks embedded in an infinite, isotropic, and homogeneous elastic medium is solved by a simple integral equation technique. Approximate expressions for the stress intensity factors, far‐field amplitudes, and scattering cross section are obtained when the wavelengths are large compared to the distance between the outer edges of the two cracks. By taking appropriate limits in these expressions, we derive some interesting and new results. The values of stress intensity factors and the scattering cross section are computed and various graphs of these physical quantities of interest are plotted.
