Contraction and optimality properties of an adaptive Legendre-Galerkin method: the multi-dimensional case

open access: yes, 2014
We analyze the theoretical properties of an adaptive Legendre-Galerkin method in the multidimensional case. After the recent investigations for Fourier-Galerkin methods in a periodic box and for Legendre-Galerkin methods in the one dimensional setting ...

Design, Experiment, and Improvement of a Quasi-Zero-Stiffness Vibration Isolation System

open access: yesApplied Sciences, 2020
This paper proposes a new kind of quasi-zero-stiffness (QZS) isolation system that has the property of low-dynamic but high-static stiffness. The negative stiffness was produced using two magnetic rings, the magnetization of which is axial.

Hardcore bosons on the dual of the bowtie lattice

open access: yes, 2010
We study the zero temperature phase diagram of hardcore bosons on the dual of the bowtie lattice. Two types of striped diagonal long-range order (striped order I and striped order II) are discussed. A state with type-II striped order and superfluidity is

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

open access: yesAdvanced Materials Technologies, EarlyView.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

Ductility Tuning via Cluster Network Characteristics of Porous Components

open access: yesAdvanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Characteristic analysis of a quasi-zero-stiffness vibration isolator

open access: yesIOP Conference Series: Materials Science and Engineering, 2018
The frequency range over which a linear passive vibration isolator is effective, is often limited by the stiffness required to support a static load. And this can be improved upon by employing nonlinear negative stiffness elements to get a low dynamic stiffness.
