From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Flow Induced Vibrations in Engineering Systems and the Control of Flow Induced Vibrations. Chaotic Vibration in Poppet Valve Circuit.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995
In the previous paper we pointed out that chaotic vibrations can occur in poppet valve circuits due to nonlinearities. The chaotic motions in the poppet valve circuits include (a) period-doubling-type chaos, (b) Lorenz-type chaos and (c) intermittent-type chaos. In this paper, period-doubling-type chaos has been investigated in detail.

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Electrified Damage in Motion Systems

Advanced Engineering Materials, EarlyView.
The electrified damage in motion systems is a fundamental framework presenting the degradation pathway arising from the coupling of electrical energy transport with mechanical contact and interfacial chemistry. The framework positions electrified damage as a distinct degradation regime with unique characteristic surface morphologies and failures of ...

Flow-Induced Vibration of a Spherical Body

, 2018
Fluids and structures are everywhere, so the interaction between them is common. Although fluid-structure interaction can be gentle and harmless, in other situations it can result in long-term structural damage or even catastrophic failure.

Advances in Micromanipulation Actuated by Vibration-Induced Acoustic Waves and Streaming Flow

Applied Sciences, 2020
The use of vibration and acoustic characteristics for micromanipulation has been prevalent in recent years. Due to high biocompatibility, non-contact operation, and relatively low cost, the micromanipulation actuated by the vibration-induced acoustic ...
