Abstract

Developed a methodical approach, algorithm and computer program for determining thermal characteristics are widely used in aviation and space technology anisotropic materials. Methodical approach is based on a solution of inverse heat conductivity problem stated as an extremal one. The effectiveness of the use of the recommended approach is illustrated by the example of recovery of the thermal conductivity tensor and volumetric heat capacity of the composite perspective on the results of physical experiments with a sample of this material.
