Following a classical plate bending theory of magneto-elasticity, we consider the scattering of time harmonic flexural waves by a through crack in a magnetically saturated plate under a uniform magnetic field normal to the plate surface. Fourier transform method is used to solve the magneto-elastic problem and the solution is expressed in terms of a pair of dual integral equations. The dual integral equations are further reduced to a Fredholm integral equation of the second kind. Numerical method is then employed to solve the Fredholm integral equation. The influence of the magnetic field on the dynamic moment intensity factor is displayed graphically.
