Magnetic fusion reactors work under a strong magnetic field. This paper deals with the electromagneto-elastic problem of an electrically conducting finite strip with a finite crack under a uniform electric current flow and a constant magnetic field. The crack disturbs the current flow and anti-plane shear stresses are caused by the interaction between the magnetic field and the disturbed current. Two problems concerning the electric current density field and the electromagneto-elastic field are formulated by means of integral transform techniques and reduced to two Fredholm integral equations of the second kind. Numerical calculations are carried out and the stress intensity factor is obtained for several values of geometrical parameters.
