Analysis of patch substructuring methods

, 2007
International audiencePatch substructuring methods are non-overlapping domain decomposition methods like classical substructuring methods, but they use information from geometric patches reaching into neighboring subdomains, condensated on the interfaces,

A method for designing desired eigenmode through changing internal force between subsystems

Nihon Kikai Gakkai ronbunshu
Vibration related to several performances such as durability and noise performance is the one of the important performances on automotive product. The technique of reshaping eigenmode is a practical way to improve the performance on the product design ...

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

Advanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

An inverse method for deriving structural modification of a subsystem based on changes in mechanical energy to allocate multiple resonant frequencies

Nihon Kikai Gakkai ronbunshu
NV (Noise and Vibration) performance is one of the key product qualities of a mechanical system. Isolating all resonant frequencies from the frequency band where excitation forces are high is an important strategy for improving NV performance. However, a

Optimizing lightweight structures with particle damping using frequency based substructuring

Design Science, 2020
In many cases, the use of damping technologies is the only option to reduce undesired vibrations. Despite various damping techniques available on the market, the design of a precise damping behaviour still needs a lot of experimental testing and ...

Thiolated Polymers in 3D Bioprinting: Control of Gelation

Advanced Materials, EarlyView.
Thiolated polymers are established as programmable bioinks for 3D bioprinting, integrating versatile crosslinking chemistries with redox‐responsive control. This work demonstrates how molecular design and external triggers define gelation kinetics, printability windows, and structural fidelity, enabling stable, high‐resolution constructs and advancing ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Interval and fuzzy eigenfrequency analysis of uncertain substructured FE models

Computer Assisted Methods in Engineering and Science, 2022
This paper uses an interval and fuzzy finite element approach for the eigenfrequency analysis of a mechanical structure with uncertain parameters. The component mode synthesis method is applied for the numerical reduction of the structure, in order to ...
