Non-linear fe modelling of seismic pounding and damped-mitigating interconnection between a r/c tower and a masonry church [PDF]

, 2013
The finite element analysis of pounding represents one of the most critical issues for the assessment of the seismic performance of R/C structures built at poor distance from adjacent buildings.

Temperature sensitive controller performance of MR dampers [PDF]

, 2009
Magnetorheological (MR) dampers can experience large temperature changes as a result of heating caused by energy dissipation, but control systems are often designed without consideration of this fact.

Improved toggle-brace viscous damper for vibration mitigation of wind turbine blade

Alexandria Engineering Journal
As wind turbine blades increase in size to capture more wind energy, the significance of effective vibration control becomes paramount. This study introduces two passive damping systems, the toggle-brace viscous damper (TBD) and the shear toggle-brace ...

Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy

Advanced Materials, EarlyView.
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks

Advanced Materials, EarlyView.
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Hysteretic damper based on the Ishlinsky-Prandtl model

MATEC Web of Conferences, 2016
In this paper we consider the mathematical model of hysteretic damper based on the Ishlinsky-Prandtl model. The numerical results for the observable characteristics such as force transmission function and “force-displacement” transmission function are ...

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

Advanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...
