The volume integral method of eddy current modeling

  • W. Scott Dunbar
Article

Abstract

The volume integral method is proposed as an alternative method for computing the impedance changes associated with eddy current measurements. In this method, the use of an appropriate Green's function for the host medium requires that integration be performed only over the volumes of defects. Although only rather simple host medium geometries are amenable to this type of modeling, the method can be linked to finite element models of more complicated geometries. In this way, the amount of finite element modeling may be minimized.
