WEBA thermoelastic material is one in which the internal energy (e) is a function only of Fand the specific entropy (η), that is e= ¯e(F,η) . For a thermoelastic material, we can show that the entropy inequality can be written as (see Appendix) ρ ∂e¯ ∂η −T η˙ + ρ ∂e¯ ∂F −σ·F−T : F˙ + q·∇T T ≤ 0 . (16)

WEBJan 5, 2012 · where ΔT and ΔS are the changes in temperature and bulk stress, respectively, and K=α/(ρC ϵ) is known as the thermoelastic constant. Kelvin’s Law provides a simple and direct link between the dynamic temperature and bulk stress and so forms the basis for experimental stress analysis by the measurement of temperature.

WEBOur conclusion is that thermoelastic effect indeed influences the dv/v. This effect should be negligible on unconsolidated materials, and play a more important role on soils and rocky materials. Removing thermoelastic effect from dv/v measurements should be easier in regions where the temperature is positive all the year. Monitoring the ...
