Tribology of ZrC Coatings and Spherical Tips Acquired with Extraordinarily Stiff, Metal Atomic Force Microscopy Probes

open access: yesAdvanced Engineering Materials, EarlyView.
In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Influence of Al content on the elastic properties and various anisotropies of AlxC rFeCoNiCu high entropy alloys base on the first-principles calculation

open access: yesMaterials Research Express, 2023
First-principles density-functional theory was used to analyze the effects of Al on the mechanical properties, stability, elastic constant, and elastic anisotropy of AlxCrFeCoNiCu (x = 0, 0.5, 1, 1.5, 2) HEAs.

Elastic Energy, Fluctuations and Temperature for Granular Materials

open access: yes, 2003
We probe, using a model system, elastic and kinetic energies for sheared granular materials. For large enough $P/E_y$ (pressure/Young's modulus) and $P/\rho v^2$ ($P/$kinetic energy density) elastic dominates kinetic energy, and energy fluctuations ...

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Elastic response of filamentous networks with compliant crosslinks

open access: yes, 2013
Experiments have shown that elasticity of disordered filamentous networks with compliant crosslinks is very different from networks with rigid crosslinks.

Measuring the Elastic Modulus of Snow

open access: yes, 2017
The elastic modulus is the most fundamental mechanical property of snow. However, literature values scatter by orders of magnitude and hitherto no cross‐validated measurements exists. To this end, we employ P wave propagation experiments under controlled

Graphene–Catechol Dental Sealant: Antibacterial and Mechanical Evaluation

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents dental sealants made with graphene and L‐DOPA‐modified graphene. L‐DOPA enhances graphene dispersion, improving sealant properties. The material shows antibacterial activity against S. mutans and L. casei, along with high strength and elasticity.

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 ...

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...
