Axisymmetric Generalized Thermoelastic Study

Rapid transient and micro-measure heat conduction problem appear more and more in engineering with the rapid development of technology, in which use traditional Fourier heat conduction law would bring some error to the result. On the foundation of summarizes and comments on Predecessors 'results, this paper research the distribution of temperature and coupled thermoelasticity of axisymmetric body using Theories of Generalized Thermoelasticity, then discuss the influence of Non-Fourier effect This paper obtain the analytical solution of one-dimension Non-Fourier heat conduction problem, and get numerical result of Non-Fourier heat conduction and thermodynamic stress in two-dimension axisymmetric body using finite element method. At the same time, this paper also bring forward a laconic and applied finite element method of calculating coupled thermoelasticity. Result show that Non-Fourier effect produce somewhat delay to the response of temperature, coupled effect also have some damping function to the change of temperature and stress. The influence of Non-Fourier and coupled effect is with relation to position of Elastic body, but limited in general measure and velocity of conduction.
