Previous theories that implicitly included heat transport predicted that temperatures were reduced in proportion to the viscous stresses in the whole region of an overdriven steady wave front in 2024 Al shocked at 80 GPa. Although there was a decrease in temperature caused by the shear stress, the decrease was very slight. A more justifiable theory that includes a heat transport term, the coefficient of which depends on the form and thickness of the effective part of a specific volume wave in the steady wave front, was then developed. The range of appropriate thicknesses of the effective part of the linear and sine forms for shocks up to 80 GPa in 2024 Al were determined. In these ranges, strain increments were sufficiently small and effective temperature rise-times were sufficiently long on the electron-phonon relaxation time scale to justify using equilibrium thermodynamics. In addition, the efficacy of the inside temperature method [Sano and Abe, J. Appl. Phys. 89, 105 (2001)] was illustrated by evaluating heat transport. The inside temperature distribution can be specified if the thickness is measured because the distribution is not influenced to a great extent by the wave form. © 2001 American Institute of Physics.
