The effect of the hydrogen coverage on the Young modulus of graphene [PDF]
, 2012 We blend together continuum elasticity and first principles calculations to measure by a computer experiment the Young modulus of hydrogenated graphene. We provide evidence that hydrogenation generally leads to a much smaller longitudinal extension upon loading than in pristine graphene.

Determining the thickness and modulus of the nano-metric interphase region using macroscopic modulus data in exfoliated polymer-clay nanocomposites [PDF]
Polymer 90 (2016) 302-308, 2017 This paper is an attempt to predict the thickness and modulus at the nanometric interphase region with the knowledge on the macroscopic Young's modulus in the polymer-clay nanocomposites. First, a systematic design of 20160 linear elastic finite element simulations are used to derive an analytical equation between the interphase thickness, the ...

Estimation of Young's Modulus of Graphene by Raman Spectroscopy [PDF]
, 2012 The Young's modulus of graphene is estimated by measuring the strain applied by a pressure difference across graphene membranes using Raman spectroscopy. The strain induced on pressurized graphene balloons can be estimated directly from the peak shift of the Raman G band. By comparing the measured strain with numerical simulation, we obtained the Young'

Magetic softening of Young's modulus of amorphous Fe90Zr10 [PDF]
, 1994 The Young's modulus and the internal friction of amorphous Fe$_{90}$Zr$_{10}$ alloy were measured near the Curie temperature using the vibrating reed technique. The modulus shows softening around $T_c\approx 227K$ and the internal friction undergoes drastic increase at $T_c$.

Investigation of the Elastic Properties of Graphenylene Using Molecular Dynamics Simulations [PDF]
Materials Research, 2016 Molecular dynamics simulations are used here to study the mechanical behavior of graphenylene under uni-directional and bi-directional loadings. The effects of nanosheet chirality and size on Young's modulus of graphenylene are investigated.

Elasticity of Diametrically Compressed Microfabricated Woodpile Lattices
Advanced Engineering Materials, EarlyView.Modulus–porosity relationship is derived for woodpile lattices with struts under diametrical compression. The formula presented here that Young's modulus is proportional to the square of the volume fraction E˜ρ2$E \sim \left(\rho\right)^{2}$ is shown to be consistent with computations and laboratory experiments on 3D‐printed samples.

First-principles study of the Young's modulus of Si <001> nanowires [PDF]
, 2006 We report the results of first-principles density functional theory calculations of the Young's modulus and other mechanical properties of hydrogen-passivated Si <001> nanowires. The nanowires are taken to have predominantly {100} surfaces, with small {110} facets.

Advanced Engineering Materials, EarlyView.AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by

Size, vacancy and temperature effects on Young's modulus of silicene nanoribbons [PDF]
RSC Adv., 2015, 5, 96052, 2015 We report results on the Young's modulus (YM) of defect-free and defective silicene nanoribbons (SNRs) as a function of length and temperature. In this study, we perform molecular dynamics simulations using the Environment-Dependent Interatomic Potential (EDIP) to describe the interaction of the Si atoms.

Advanced Engineering Materials, EarlyView.A metallic implant's higher stiffness compared to the surrounding bone leads to stress shielding problems, causing bone density reduction and bone growth interference in pediatric patients. 3D‐printed triply periodic minimal surface structures present a promising engineering solution.
