N2 - The axisymmetric dynamic response of a penny-shaped crack in an elastic conductor under an impulsive electric current flow and a constant axial magnetic field is analyzed. The axial current flow is disturbed by the presence of the crack and the torsional shear stresses are caused by the interactions between the magnetic field and the disturbed current. Laplace and Hankel transforms are used to reduce the electromagnetoelastic problem to a Fredholm integral equation of the second kind in the Laplace transform plane. A numerical Laplace inversion routine is used to recover the time dependence of the solution. Numerical results on the dynamic stress intensity factor are obtained and are presented in a graphical form.
