“…The three-dimensional model utilizes quarter symmetry and is based on Edge-Based Formulation, which is accurate and suitable for nondestructive testing applications. The accuracy of the finite element solution, implemented in ANSYS APDL, has been confirmed by comparing the results with those reported by Li et al (2007) under specific probe geometry, sample conductivity, and excitation. The total number of elements in the model are 108873, and is run on 2.2 GHz processor with 2GB RAM.…”

“…If R c is close to 0, the n plots consisting of (x i , y i ) are not arranged on a line, and it can be concluded that there is no correlation between them. To calculate R c for the linear relationship between 蟽 b and X/X 0 MPa , they are substituted for x and y in (17). From Fig.…”

“…These equations apply to an infinite solution region, which presents us with some numerical difficulties. Applying the extended truncated region eigenfunction expansion (ETREE) method [17,18] which, based on the analytical method of Theodoulidis and Kriezis [19], assumes that the solution region is finite in the radial direction, (4) and (7) can be rewritten as follows [19]:…”

“…The previously-defined pulse is applied to a driving coil of the ECS, and the primary magnetic flux density (Bair) is produced. In consequence, PEC is induced on the surface of the anchor head and the secondary magnetic flux density ( Bs) is generated which varies with the magnetic permeability of the surface and the current level of T. Then, the resultant magnetic flux density B can be expressed in Equation (2) [15].…”
