Energy Policy, 1976
Abstract It has become a commonplace that growth of energy demand and GNP have gone hand in hand. In examining the energy elasticity coefficients of a large number of European countries, however, the authors conclude that, not only is there very little sign of any pattern emerging but that there seems little or no evidence for the view that the ...

Elastic strain energy of inhomogeneous solids
Physical Review B, 1995A two-phase elastically inhomogeneous coherent mixture of two phases with the transformation-induced crystal lattice misfit is considered under the loaded and unloaded conditions. It is assumed that the constituent phases particles, composing the mixture, have the structural pattern of an arbitrary morphology but the system is macroscopically ...

On the energy of an elastic rod
Journal of Applied Mathematics and Mechanics, 1981Abstract It is shown that the general geometrically nonlinear problem of the three-dimensional theory of elasticity for a rod can be split into a nonlinear “one-dimensional” problem (one-dimensional theory of rods) and a linear “two-dimensional” problem. A number of constant “effective” elastic characteristics of the rod is in the equation of the one-

Energy demand elasticities and weather worldwide
Economia Politica, 2015The purpose of this paper is to empirically estimate a model of aggregate residential and commercial energy demand elasticities, taking into account capital stock and climatic effects. We model a theoretically founded non-linear energy demand system, the generalized almost ideal, for the most important 117 countries in the world, which represent around

On the use of energy elasticities
Energy, 1979Abstract The change in energy consumption associated with a change in economic activity, i.e. the energy elasticity, has been used as the single most significant parameter in forecasting energy consumption. It has been found that the change in elasticity with time reflects shifts in energy uses in the economy.

Energy propagation in a deformed elastic material
Archive for Rational Mechanics and Analysis, 1972Resultant material and spatial energy propagation vectors are defined for waves of small amplitude superposed on large static deformations in elastic materials of arbitrary symmetry. It is shown that the resultant material energy propagation vector is in the direction of the normal to the slowness surface and hence in that of the bicharacteristics.

The energy of elastic defects: a distributional approach
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1994Abstract An analysis of moving defects in homogeneous elastic materials is given in this paper. The laws of linear momentum, moment of momentum and energy are obtained in a distributional form. The motion of singularities gives rise to new terms in these balance laws.

CdSe Nanoparticle Elasticity and Surface Energy
Nano Letters, 2009The acoustic phonon modes of colloidal CdSe nanoparticles in solution (293 K) are passively measured by a third order ultrafast heterodyne cross-polarized transient grating measurement. Using the observed size-dependence of the acoustic phonon frequency, the elastic properties of the nanoparticles are determined.

Elastic energy of protein-DNA chimeras
Physical Review E, 2009We present experimental measurements of the equilibrium elastic energy of protein-DNA chimeras, for two different sets of attachment points of the DNA "molecular spring" on the surface of the protein. Combining these with measurements of the enzyme's activity under stress and a mechanical model of the system, we determine how the elastic energy is ...

More on the Output Elasticity of Energy Consumption
The Journal of Industrial Economics, 1972IN work published in I968, Adams and Miovic' noted that the output elasticity of energy consumption (commonly called the energy coefficient) was a somewhat amorphous parameter, differing substantially between countries and changing over time. They demonstrated that if energy statistics were adjusted to take account of the different efficiencies of the ...
