Simplified Modelling the Demagnetization of H-Bar with Method of Moments

Abstract

Calculation of distribution of flux density in the constructional elements is required in non-destructive testing. Paper presents the simplified method of calculation of flux density distribution in H-bar based on the generalization of the method of moments. In opposite to finite elements method, the method of moments doesn’t require to solve ill-posed differential equations. As a result, the solution together with software presented in the paper can be helpful in the process of non-destructive evaluation of the mechanical stress distribution in ferromagnetic construction elements.
