Investigation of the Elastic Modulus of Polymer Sleepers Under a Quasistatic and Cyclic Loading

Civil and Environmental Engineering, 2019
In ballasted track, the wheel load is transmitted to the subgrade via sleepers commonly made of impregnated wood, prestressed concrete, steel or recently developed polymer sleepers.

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Elastic collapse in disordered isostatic networks

, 2012
Isostatic networks are minimally rigid and therefore have, generically, nonzero elastic moduli. Regular isostatic networks have finite moduli in the limit of large sizes.

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

Advanced Engineering Materials, EarlyView.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Elastic Bending Modulus of Single-Layer Molybdenum Disulphide (MoS2): Finite Thickness Effect

, 2013
We derive, from an empirical interaction potential, an analytic formula for the elastic bending modulus of single-layer MoS2 (SLMoS2). By using this approach, we do not need to define or estimate a thickness value for SLMoS2, which is important due to ...

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films

Advanced Engineering Materials, EarlyView.
Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

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

Materials 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 bending modulus of monolayer graphene [PDF]

Journal of Physics D: Applied Physics, 2009
A new formula for elastic bending modulus of monolayer graphene is derived analytically from an empirical potential for solid-state carbon-carbon bonds. Two physical origins are identified for the non-vanishing bending modulus of the atomically thin graphene sheet, one due to the bond angle effect and the other resulting from the bond order term ...

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Emergence of rigidity at the structural glass transition: a first principle computation

, 2010
We compute the shear modulus of structural glasses from a first principle approach based on the cloned liquid theory. We find that the intra-state shear-modulus, which corresponds to the plateau modulus measured in linear visco-elastic measurements ...
