Abstract: Reliable quantitative identification of material characteristics determines the validity of all engineering computations, namely those connected with the modelling and simulation of non-stationary problems in heat transfer and related processes of continuum mechanics. Unfortunately, identification problems are often much more complicated than the original direct ones, thus very special geometrical configurations and physical conditions are needed. This paper demonstrates the identification of basic thermal characteristics of building materials in the linearized Fourier equation with (a priori unknown) boundary heat transfer, motivated from real direct and inexpensive non-stationary measurements, applicable both in a laboratory and in situ, based on the conjugate gradient and least squares techniques. This approach can be generalized to a rather wide class of identification problems, including the uncertainty analysis.
