Learning Corrections for Hyperelastic Models From Data

Frontiers in Materials, 2019
Unveiling physical laws from data is seen as the ultimate sign of human intelligence. While there is a growing interest in this sense around the machine learning community, some recent works have attempted to simply substitute physical laws by data.

First-Principles Atomistic Thermodynamics and Configurational Entropy

Frontiers in Chemistry, 2020
In most applications, functional materials operate at finite temperatures and are in contact with a reservoir of atoms or molecules (gas, liquid, or solid).

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.

Elastic, thermal expansion, plastic and rheological processes - theory and experiment [PDF]

, 2015
Rocks are important examples for solid materials where, in various engineering situations, elastic, thermal expansion, rheological/viscoelastic and plastic phenomena each may play a remarkable role.

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 ...

Hawking radiation without black hole entropy [PDF]

, 1997
In this Letter I point out that Hawking radiation is a purely kinematic effect that is generic to Lorentzian geometries. Hawking radiation arises for any test field on any Lorentzian geometry containing an event horizon regardless of whether or not the ...

In silico estimates of the free energy rates in growing tumor spheroids [PDF]

, 2010
The physics of solid tumor growth can be considered at three distinct size scales: the tumor scale, the cell-extracellular matrix (ECM) scale and the sub-cellular scale. In this paper we consider the tumor scale in the interest of eventually developing a

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 ...
