Modeling of Pulsed Thermography in Anisotropic Media

Abstract

Thermography is increasingly being used as an NDE tool to detect damage (corrosion, delamination, water incursion) in materials. Many empirical results have been collected over the years that allow the operator to get a "feel" for the extent of the problem. No simple models exist that provide quantitative results. Finite element analysis is done but is laborious and does not provide simple relationships which can be utilized for quantitative analysis of real world problems. In this report, we have performed a series of experiments where we vary many of the key parameters and perform simple thermographic modeling to find useful mathematical relationships.
