A porous nanotube network structure of metallic carbon

open access: yesResults in Physics, 2021
A porous nanotube network structure of carbon allotrope was designed, denoted as P4/mmm C96. Besides its structure similar to carbon nanotubes, the most interesting thing about P4/mmm C96 is that its band structure is metallic. The shear modulus G, Young’

Pressure Dependence of the Elastic Moduli in Aluminum Rich Al-Li Compounds

open access: yes, 1992
I have carried out numerical first principles calculations of the pressure dependence of the elastic moduli for several ordered structures in the Aluminum-Lithium system, specifically FCC Al, FCC and BCC Li, L1_2 Al_3Li, and an ordered FCC Al_7Li ...

Acoustic scattering from a strained region [PDF]

open access: yes, 2006
A composite material consists of a rubber filled with gas-filled microspheres. In underwater applications it is compressed hydrostatically by a pressure that may be not insignificant compared with the shear modulus of the rubber, so large strains are ...

A new mechanism for low and temperature-independent elastic modulus

open access: yesScientific Reports, 2015
The first Elinvar alloy, FeNiCr, which has invariant elastic modulus over a wide temperature range, was discovered almost 100 years ago by Guillaume. The physical origin of such an anomaly has been attributed to the magnetic phase transition taking place
