Abstract

A fast forward scheme based on the Finite Element Method (FEM) and databases is proposed and developed for the rapid computation of Direct Current Potential Drop (DCPD) signals under condition of 3D FEM analysis for Nondestructive Testing (NDT) of Metallic Foam to reduce computer burden. Comparison of numerical results of the present method with those of full FEM code and experimental results of metallic foam indicates that the proposed novel fast forward scheme can predict DCPD signals accurately and over 100 times faster.
