Abstract :
The challenges associated with finite element modeling of a tight crack in an otherwise large geometry encountered in a typical nondestructive evaluation application are considered. A novel approach for decomposing the modeling of velocity induced fields in a conducting ferro- or nonferromagnetic material is presented
