3D Eddy Current Testing by FEM for detection of crack’s in materials KahinaChabane1,a* , Salaheddine Harzallah2,b and Mohamed Chabaat3,c, 1,2,Doctorate,3Professor, Built Environmental ResearchLab., Civil Engineering Faculty, University of Sciences and Technology HouariBoumediene, B.P 32 Bab Ezzouar, Algiers 16111 Algeria.
Abstract In this paper, we present a nondestructive Testing by sensor Eddy current is used as a tool to control cracks and micro-cracks in materials.
This method has emerged as one of the most efficient technique for prospecting cracks in materials, evaluating and analyzing crack’s growth.

This indicates that the failure criterion for brittle materials under compression is effective and applicable.
For the case of materials without pre-existing macrocracks, the failure criterion is identical with the well known Coulomb–Mohr criterion.

Material that was observed to possess such properties was Phase Change Material.
PCM were identified to be materials that can store or release large amounts of heat energy during phase change.
Thermo-Magnetic materials used instead of PCM in a thermo magnetic engine setup. 2.
