Abstract

Algorithms and software are developed to analyze thermophysical characteristics of anisotropic materials basing on a solution of inverse heat conductivity problem stated as an extremal one. An efficiency of the technique is demonstrated as applies to a recovery of the thermal conductivity tensor and volumetric heat capacity basing on physical experiment results. The recovery is carried out for an orthotropic material built on carbon fibers and epoxy binder. This material is promising for design of aerospace structures.
