Current situation of research on test methods for elastic modulus and Poisson’s ratio of single crystal superalloys

open access: yesJournal of Aeronautical Materials, 2019
In view of the anisotropic characteristics of elastic constants of single crystal superalloys and other materials, this paper summarizes two main existing testing methods for measuring elastic moduli and Poisson’s ratio of single crystal superalloys ...

Comparison of elastic moduli from seismic diving-wave and ice-core microstructure analysis in Antarctic polar firn

open access: yesAnnals of Glaciology, 2019
We compared elastic moduli in polar firn derived from diving wave refraction seismic velocity analysis, firn-core density measurements and microstructure modelling based on firn-core data.

Theorems of relations between elastic modulus and the stiffness matrix coefficients of isotropic homogeneous finite elements [PDF]

open access: yesEPJ Web of Conferences, 2019
This paper formulates theorems establishing a mutually unambiguous relation between the stiffness matrix coefficients and elastic moduli of an isotropic homogeneous finite element (FE), which allows explicitly expressing the elastic moduli of the FE via ...

Nonaffine Correlations in Random Elastic Media [PDF]

open access: yes, 2005
Materials characterized by spatially homogeneous elastic moduli undergo affine distortions when subjected to external stress at their boundaries, i.e., their displacements $\uv (\xv)$ from a uniform reference state grow linearly with position $\xv$, and ...

Effect of PbO on the elastic behavior of ZnO–P2O5 glass systems

open access: yesResults in Physics, 2016
A series of ternary phosphate glasses in the form of 40(P2O5)–(60 − x)ZnO–xPbO and 50(P2O5)–(50 − x)ZnO–xPbO where x = 0–60 mol%, have been successfully prepared by conventional melt quenching technique.

How does static granular matter re-arrange for different isotropic strain rate? [PDF]

open access: yesEPJ Web of Conferences, 2021
The question of how soft granular matter, or dense amorphous systems, re-arrange their microstructure under isotropic compression and de-compression, at different strain rates, will be answered by particle simulations of frictionless model systems in a ...

Using resonance to measure the independent elastic constants of problematic materials such as elastomers [PDF]

open access: yesJASA Express Letters, 2021
The determination of the elastic constants for a solid material may be conveniently accomplished by measuring resonances corresponding to the elastic normal modes of a sample. Isotropic materials should be particularly straightforward, since they involve

The permeability and elastic moduli of tuff from Campi Flegrei, Italy: implications for ground deformation modelling [PDF]

open access: yesSolid Earth, 2014
The accuracy of ground deformation modelling at active volcanoes is a principal requirement in volcanic hazard mitigation. However, the reliability of such models relies on the accuracy of the rock physical property (permeability and elastic moduli ...

Study on dynamic and static elastic moduli of shale oil by different loading methods

open access: yesUnconventional Resources, 2023
Experiments on the dynamic and static elastic parameters under distinct loading conditions help clarify the effects of loading rate and strain amplitude on dynamic and static elastic moduli, and gain further insight into the moduli.
