Methods for Evaluating Thermophysical Properties of Functionally Gradient Material

Abstract

The temperature response in a functionally gradient material (FGM), subjected to pulsewise heating at the front surface, is evaluated. The approximate solution for the temperature response is investigated by comparing it with an exact analytical solution for the FGM in which the thermophysical properties have logarithmic profiles. By using these solutions the thermophysical properties are evaluated as the total properties for the FGM.
