英文摘要	Finite element analysis on the coupled thermoelastic behavior in an aluminum thin film is demonstrated using implicit Newmark algorithm. The generalized dynamic theory of thermoelasticity is applied to solve both the equation of motion and the energy equation. The results show that the ratio between the relaxation times tau(0) and tau(2) Controls the transition of the temperature evolution and thermal deformation among over-diffusive, diffusive, wavelike and wavy behaviors of heat conduction in time domain. The abnormality of temperature evolution and thermal deformation for wavy heat conduction is discussed. The applicability of the exponential and Gaussian form for the dynamic thermal expansion is illustrated primarily. (c) 2006 Elsevier B.V. All rights reserved.
