Abstract
A path-independent integral which is denoted by je, is introduced for the 2-dimensional crack problems in the homogeneous isotropic conductor in which the steady current flows. By utilizing the je-integral the distributions of the electric potential, current density and the Joule heating rate near the crack tip are derived. It is shown that the je-integral provides a parameter which dominates the distributions of the electric potential and current density near the crack tip as the square of the amplitude.
