Finite Element Analysis 

FEAFinite Element Analysis refers to a modelling approach used to investigate the impact of physical effects on components. The component is divided into a mesh consisting of a large number of small elements. Equations are solved for each small element within the mesh, in turn, and the results are combined to calculate the overall behaviour of the component. FEA is used, among other approaches, to predict displacement, mechanical stresses, strains, heat transfer and fluid flow.

FEA is used in NDT to model the performance of a number of techniques, for example thermography, ultrasonic responses from rough defects and electromagnetic parameters, for the analysis of techniques such as alternating current-potential drop (ACPD), eddy currents and magnetic flux leakage.
