Driven colloidal monolayers: static and dynamic friction

, 2014
Trapping and dragging colloidal monolayers in two-dimensional optical lattices is offering the possibility to mimic friction between crystals (or even quasicrystals) visualizing directly the intimate mechanisms of sliding friction, with the additional ...

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Subloading-overstress friction model

Nihon Kikai Gakkai ronbunshu, 2014
The subloading-friction model proposed formerly is capable of describing the transition from the static to the kinetic friction and the recovery of static friction, which leads to the negative rate-sensitivity, i.e.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Wetting transition: Macroscopic roughness, static friction, and energy barrier

Physical Review Research
When a droplet is deposited on a rough solid substrate, the classic Cassie-Wenzel theory (CWT) is often used to describe the wetting states. However, CWT fails to explain experimental observations of high static friction on hydrophobic surfaces with a ...

GCL-LLDPE geomembrane interface friction angle evaluation and stability analysis of a valley fill leach pad project [PDF]

E3S Web of Conferences
The Los Chancas mining project, initiated in 1998, is a copper mine focused on extracting copper sulfides and oxides. In 2020, a mine plan update required a review of the constructability design and an evaluation of the Permanent Leach Pad and Filtered ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.
