This paper proposes an inverse analysis procedure to estimate unknown thermal properties and heat transfer coefficient in transient heat conduction. The Laplace-transform boundary element method an the standard optimization technique are used to analyze the inverse problem. It is assumued that the time-series data of temperature measured at some selected points can be used for inverse analysis. The inverse problem in reduced into and optmum problem in which a set of parameters describing unknown values should be estimated. Numerical experiment is carried out to investigate the influence of measurement errors on the estimation results. The usefulness of the proposed methos of inverse analysis is demonstrated from numerical simulation for several examples. It is revealed that the estimation results are greatly influenced by errors included in the measured data.
