Strong Transient Thermal Shock Under Axisymmetric Elastic Body Thermoelastic Coupling Research

Non-traditional heat transfer effect, which is possible to appear in rapid transient heat transfer process is gradually growing into a new research focus due to its great practical potentiality and academic significance. Analytical solution and numerical simulation of non-Fourier heat conduction models summarizes and comments on predecessors' results and obtains the analytical solution of hyperbolic heat conduction model for a hollow cylinder with inner and outer boundary surfaces subjected to sudden temperature rise. Conditions for producing evident non-Fourier heat conduction behavior are discussed and some methods for non-Fourier temperature control are proposed. Then an effective method is presented for gaining the distribution of the dynamic thermoelastic stress in a hollow cylinder subjected to thermal shock, one easily obtains the exact solution for the transient waves caused by thermal shock, the response and distribution of thermodynamic stresses in a hollow cylinder are also solved by means of the analytical method. With the assistance of some necessary theoretical analysis, systematic research on non-Fourier effect in thermal shock is carried out.
