    Opis:
    This article deals with the possibility for increasing of the informational value of a response signal using tilt-shift eddy current probe. Numerical simulations based on the FEM method using the OPERA 3D software as well as gained experimental results are presented. The simulated cracks are evaluated at the selected eddy current probe tilts and shifts with respect to conductive plate to obtain additional data needed for its evaluation and localization. Obtained simulation results are compared and discussed with the experimental results.

    Opis:
    Casting is the manufacturing process of pouring the hot liquiduos state metal in to the mold cavity and then allowed it to solidify to obtain the final casting. There are many defects are found in the casting components during the inspection. Some defects are tolerated while others are required to repair. Otherwise the casting component is to be eliminated due to the poor quality level. The aim of the non-destructive inspection is to determine, the flaws, discontinuities on the material, and characteristics of the material. Based on the results by non-destructive evaluation the personnel take the decision on the material object is to be accepted or not as per the criteria. In this paper the hardness attribute of the case hardened AISI 4130 steel samples are studied using Vickers Hardness test. Then the hardness property is correlated with the Eddy Current Testing method. According to the acceptance criterion the suitability of the material is analyzed for the corresponding application or not. In this paper Eddy Current Testing response is analyzed for the AISI 4130 samples to determine the mechanical properties of the material. The main objective of the paper is to investigate the effect of the hardness property of the casting material during various case depth obtained via case hardening process. This technique is effective and best practice for the heat treatment shop floors. By this technique the results are investigated based on the cracks and microstructure of the casting material.

    Opis:
    In this paper we present the results of simulations of the Magnetic Induction Tomography (MIT) forward problem. Two complementary calculation techniques have been implemented and coupled, namely: the finite element method (applied in commercial software Comsol Multiphysics) and the second, algebraic manipulations on basic relationships of electromagnetism in Matlab. The developed combination saves a lot of time and makes a better use of the available computer resources.

    Opis:
    This work deals with the inverse problem associated to 3D crack identification inside a conductive material using eddy current measurements. In order to accelerate the time-consuming direct optimization, the reconstruction is provided by the minimization of a last-square functional of the data-model misfit using space mapping (SM) methodology. This technique enables to shift the optimization burden from a time consuming and accurate model to the less precise but faster coarse surrogate model. In this work, the finite element method (FEM) is used as a fine model while the model based on the volume integral method (VIM) serves as a coarse model. The application of the proposed method to the shape reconstruction allows to shorten the evaluation time that is required to provide the proper parameter estimation of surface defects.
