Revisiting the thermodynamics of hardening plasticity for unsaturated soils [PDF]

, 2010
A thermodynamically consistent extension of the constitutive equations of saturated soils to unsaturated conditions is often worked out through the use a unique 'effective' interstitial pressure, accounting equivalently for the pressures of the ...

Thermodynamic explanation of solid-state reactions in synthesis process of CoSb3 via mechanical alloying

Acta Physica Sinica, 2006
CoSb3 powders were synthesized by mechanical alloying (MA) with Co and Sb powders as starting materials. The influence of milling speed and duration on the solid reaction were systematically studied. The XRD results indicated that the CoSb3 phase increased with prolonged MA-time, but extensive MA resulted in the appearance of CoSb2 and the ...

Statistical Thermodynamics of Polymer Quantum Systems [PDF]

, 2011
Polymer quantum systems are mechanical models quantized similarly as loop quantum gravity. It is actually in quantizing gravity that the polymer term holds proper as the quantum geometry excitations yield a reminiscent of a polymer material.

Thermodynamic analysis of the change of solid solubility in a binary system processed by mechanical alloying

Journal of Alloys and Compounds, 2009
Abstract Using a non-equilibrium process, it is possible to extend the solid solubility range in metallic systems. Therefore, the main objective of this work was to apply a thermodynamic model to predict the change in the solubility limit of systems with positive enthalpy mixing (Cu–Cr and Fe–Cu) processed by mechanical alloying.

Atomic thermodynamics and microkinetics of the reduction mechanism of electrolyte additives to facilitate the formation of solid electrolyte interphases in lithium-ion batteries

RSC Advances, 2020
The formation of a solid electrolyte interphase (SEI) between the anode surface and the electrolyte of lithium-ion batteries (LIBs) has been considered to be the most important yet the least understood issue of LIBs.

Incommensurate Crystallization of Neutron Matter in Neutron Stars

East European Journal of Physics, 2020
The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to ...

Heat-exchange statistics in driven open quantum systems

New Journal of Physics, 2014
As the dimensions of physical systems approach the nanoscale, the laws of thermodynamics must be reconsidered due to the increased importance of fluctuations and quantum effects.

Solid-fluid dynamics of yield-stress fluids

, 2014
On the example of two-phase continua experiencing stress induced solid-fluid phase transitions we explore the use of the Euler structure in the formulation of the governing equations.

Heat–fluid–solid coupling model for gas-bearing coal seam and numerical modeling on gas drainage promotion by heat injection

International Journal of Coal Science & Technology, 2019
Improving the absorbed gas to active desorption and seepage and delaying gas drainage attenuation are considered as key methods for increasing drainage efficiency and gas output. According to the solid mechanics theory, the nonlinear Darcy seepage theory

Thermodynamics of volume collapse transitions in cerium and related compounds

, 2005
We present a non-linear elastic model of a coherent transition with discontinuous volume change in an isotropic solid. The model reproduces the anomalous thermodynamics typical of coherent equilibrium including intrinsic hysteresis (for a pressure driven
