Abstract

The magnetoelastic plane problems of an infinite soft ferromagnetic strip containing two symmetric edge cracks normal to the boundary are formulated in terms of a singular integral equation. The main purpose of the paper is to investigate the effect of magnetic fields on the stress intensity factors. The solutions of the problems are obtained for a uniform magnetic field normal to the crack surfaces and for uniaxial tension applied to the strip away from the crack region. A strain gage method is also employed in tensile tests to determine the magnetic stress intensity factors. The theoretical results for the plane stress case agree very well with the experimental values.
