Diffraction of P-wave by crack in an elastic strip at asymmetric position

Scattering of P-wave by a Griffith Crack in a long elastic strip situated at an asymmetric position has been studied in this paper. Using Fourier transform, the mixed boundary value problem has been reduced to the solution of dual integral equations which finally has been reduced to the solution of a Fredholm integral equation of second kind. Solving this integral equation numerically, stress intensity factors have been calculated and illustrated graphically to show the effect of asymmetry of position of the crack.
