abstract

The problem of the elastic stress and induced magnetic field concentration near the vertex of a compound wedge is modeled and investigated. The wedge is made of two isotropic dielectric soft-ferromagnetic materials and is immersed in a static magnetic field. By using eigenfunction series expansion technique, the components of the magnetoelastic stresses and the disturbed magnetic field near the vertex are determined. It is shown that in that region the magnetic permeability and the applied magnetic field have a strong influence on the elastic and Maxwell stresses concentration. The results are instrumental toward actively controlling the stress concentration intensity via the applied magnetic field.
