Analysis of Flow-, Thermal- and Structural-Interaction of Hypersonic Structures Subjected to Severe Aerodynamic Heating

Abstract

This first annual report presents progress in the modelling of hypersonic fluid-thermal-structural interaction. In this phase of the effort, the basic mechanisms of heat transfer and fluid-structure interaction were identified. Mathematical models for heat transfer, structural deformation and fluid flow analysis were formulated. New unified viscoplastic theories were adapted for the modelling of complex visco-elasto-plastic structural deformation, with temperature-dependent material properties. A general procedure for the analysis of fluid-thermal-structure interaction was formulated, and relevant finite element codes were developed. These problems were applied in the solution of representative examples of thermo-structural analysis of structures subject to aerodynamic heating.
