The thermoelastic effect in PMMA

Journal of Materials Science, 1974
The thermoelastic effect has been measured in polymethylmethacrylate under both tensile and compressive uniaxial stress and the resulting temperature change for a known applied stress has been used to calculate the linear expansion coefficient of PMMA over a range of temperatures from 295 to 355 K and uniaxial stress in the elastic range using the ...

Microscopics of the thermoelastic effect

Thermochimica Acta, 1994
Abstract The micromechanism of the thermoelastic effect (changes in temperature of a solid on its adiabatic elastic loading) is treated using the model of a loaded anharmonic oscillator. Loading leads to changes in frequency and, hence, to changes in the oscillation energy of the oscillators, thereby changing the temperature of a solid.

The thermoelastic effect in rigor muscle of the frog

Journal of Muscle Research and Cell Motility, 1986
Small length changes were imposed on pairs of sartorius muscles from Rana temporaria and Rana pipiens in rigor and the mechanical and thermal responses studied. Rigor was induced by soaking the muscles overnight at 0 degrees C in a physiological salt solution containing 1.5 mM sodium azide and 0.4 mM sodium iodoacetate. Tension was measured at both the

Electromagnetic Effects in Thermoelastic Materials

Mathematics and Mechanics of Solids, 2002
It is an old idea in electromagnetic theory that the æther relations holding in vacuum should also apply in matter. However, this is not commonly used in formulating theories of electromagnetic effects in materials. To be formulated here are theories of magnetic and electric effects in deformable solids based on this idea.

Anomalous thermoelastic effect in silicon

Solid State Communications, 1981
Abstract The equations of visco and thermoelasticity are discussed and the dispersion relation for a cubic material presented. The thermoelastic contribution to the acoustic attenuation in silicon is computed from 1 – 300K. Strong attenuation anomalies associated with negative thermal expansion are found in the vicinity of 17K and 125K.

Thermoelastic effects in brakes

Wear, 1980
Abstract A one-dimensional thermoelastic analysis is applied to the results of brake dynamometer experiments. The object is to determine if such an analysis can be used to predict the appearance of hot spots on the wheel surface. The results indicate that while the theory explains some of the experimental results, it is still far from quantitatively ...

Energetics of the thermoelastic effect in solids

Physics of the Solid State, 1998
The dependence of the temperature on the external adiabatic deformation is determined for a one-dimensional model of a solid — chains of atoms with an anharmonic interaction. The resulting dependences of the average kinetic and potential components of the internal energy on this deformation are compared with a model of adiabatic loading of a single ...

End effects in thermoelasticity

Mathematical Methods in the Applied Sciences, 2001
This paper concerns spatial decay bounds of the energy for a linear dynamical problem of thermoelasticity in a semi-infinite cylindrical region. It is proved that the decay is the exponential of a polynomial of second order of the distance. The case of variable cross-section is sketched.

The thermoelastic effect in glassy polymers

Journal of Polymer Science: Polymer Physics Edition, 1978
AbstractThe thermoelastic effect has been measured in compression on four glassy polymers; namely, polystyrene, poly(methyl methacrylate), polycarbonate, and epoxy resin. Quantitative results have been obtained for the first time on three of these polymers.

Thermoelastic effects in disperse systems

Journal of Engineering Physics, 1986
We devised a continual theory of the thermoelasticity of a disperse medium consisting of a homogeneous matrix with spherical inclusions of some other material distributed in it.
