COMPUTATIONAL APPROACHES TO SOME INVERSE PROBLEMS FROM ENGINEERING PRACTICE

Development of engineering structures and technologies frequently works with advanced materials, whose properties, because of their complicated microstructure, cannot be predicted from experience, unlike traditional materials. The quality of computational modelling of relevant physical processes, based mostly on the principles of classical thermomechanics, is conditioned by the reliability of constitutive relations, coming from simplified experiments. The paper demonstrates some possibilities of computational identification of such relations, namely for heat and mass transfer, coming from original experimental and numerical results obtained at the Brno University of Technology, in selected engineering applications.
