Abstract: A new approach for computing fracture mechanics
parameters such as the Stress Intensity Factor (SIF) and the Energy Release
Rate (J) by measuring and testing related Eddy currents is presented. These
parameters are evaluated using the variation of the impedance. In the
process, a magnetic vector is formulated from the theoretical set up and
obtained results from relevant applications are checked for the theory
consistency. Besides, cracks detection as well as their propagationis are studied
through the two parameters SIF and J-integral. A simulation by a numerical
approach using Finite Element discretization of 3-D governing equations is
employed to detect damaged zones and cracks. Obtained results are compared
and agreed with those of other researchers.
