Identification of the thermophysical characteristics of materials

From a unified methodological standpoint, the coefficient of the inverse problem of determining the thermophysical characteristics of a material from temperature measurements at its depth in the approximation of a semi-infinite body, single-layer and two-layer (with a layer of an ideal conductor) plate of finite thickness has been solved. The proposed technique does not employ operations of the smoothing of experimental data and allows one to remove the restrictions on the choice of the heating regime of the specimen of the material and to expand the range of measurements by the Fourier number.
