Thermal Characterization of Functionally Graded Materials: Design of Optimum Experiments

摘要

An optimum experimental design applied to the measurement of thermal properties in functionally graded materials is studied. As a first step, a material with linearly varying thermal properties is analyzed, and several different transient experimental designs are discussed. An optimality criterion, based on sensitivity coefficients, is used to identify the best experimental design. Simulated experimental results are analyzed to verify that the identified best experimental design has the smallest errors in the estimated parameters. This procedure is general and can be applied to design of experiments for a variety of materials.
