Dynamic response of a rod due to a moving heat source under the hyperbolicheat conduction model

The dynamic thermal and elastic behavior of a rod due to a moving heat sour ce are investigated. The hyperbolic heat conduction model is used for the p rediction of the temperature history. Thermally induced displacements and s tresses are determined. An analytical-numerical technique based on the Lapl ace transformation and the Riemann-sum approximation is used to calculate t he temperature, displacement and stress distributions within the rod. The e ffects of different parameters such as the moving source speed, the convect ion heat transfer coefficient are studied and presented. (C) 2001 Academic Press.
