Numerical analysis of low-Reynolds-number flow past an array of pillars with surface slip

Nihon Kikai Gakkai ronbunshu
In the development of micro- and nano-fluidic devices incorporating nanopillar structures to create nanoscale confined flow paths, it is important to consider the slip velocity on the pillar surface, which reflects the local wettability.

Fundamental characteristics of flat thrust bearing with partial placement of slip areas

Nihon Kikai Gakkai ronbunshu, 2023
The pressure for supporting the bearing load is induced by the generation of discontinuity of the shear flow rate in each region only by arranging areas in the slip direction with different slipperiness of fluid.

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

Advanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

Advanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

The effective slip length and vortex formation in laminar flow over a rough surface [PDF]

, 2009
The flow of viscous incompressible fluid over a periodically corrugated surface is investigated numerically by solving the Navier–Stokes equation with the local slip and no-slip boundary conditions.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
