Abstract

The elastic state around a crack moving perpendicular to under an applied magnetic field is considered. The model considers a soft magnetic ferroelastic body and incorporates a realistic (nonlinear) susceptibility. A Fourier transform method is used to reduce the mixed boundary value problem to two pairs of dual integral equations, the solution of which has a closed form. The analysis shows the stress intensity factor varies with crack velocity (an unexpected result) and magnetic field.   The implications of these results on mechanical behavior will be discussed.
