EN

A stochastic finite element method was applied in the case of 2D magneto dynamic equation to study the detection and evaluation of harmful defect in a conductive structure by InSb Hall sensor and Eddy Currents Non Destructive Testing Technique. The defect is considered as a degradation of physical properties of the material. The electrical conductivity is considered as random variable inside the defect area which is generated using Monte-Carlo method. A statistical treatment was used to study the evaluation of inverse problem. Several global parameters are calculated and discussed.
