Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

open access: yesAdvanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Evolution of frictional slip behavior on shale surface using friction reducers

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
The shale-on-shale COF was measured in a pin-on-disk tribometer for dry and fluid (DI water, polymer-based anionic commercial oilfield friction reducer, and carbon nanodots solution) saturated conditions under a constant load of 15 N and at varying ...

A Novel Contact Resistance Model for the Spherical–Planar Joint Interface Based on Three Dimensional Fractal Theory

open access: yesFractal and Fractional
In order to obtain the contact resistance of relay contacts more accurately, a novel contact resistance model for the spherical–planar joint interface is constructed based on the three-dimensional fractal theory.

Fabrication Routes for Ionic Conducting Fiber Strain Sensors

open access: yesAdvanced Engineering Materials, EarlyView.
Ionic conducting fiber strain sensors (ICFSs) offer compliant, textile‐integrable sensing. Thus far, the commercialization of ICFSs has been constrained by fiber fabrication routes. This review provides a fabrication‐centric analysis of ICFSs correlating processing strategies with material properties and scalability.

Trends in Computational Contact Mechanics

open access: yes, 2011
Contact mechanics is a science that has a great impact on everyday life and is present in many different fields. These include civil, mechanical and environmental engin- eering, but also medicine since locomotion as well as functional joints do not work ...

Partial slip contact between a rigid punch with an arbitrary tip-shape and an elastic graded solid with a finite thickness

open access: yes, 2013
In contrast to the case of a graded half-space, a nonlinear plane strain partial slip model between a rigid punch with an arbitrary tip-shape and a finite graded solid is investigated.

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

open access: yesAdvanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.
