A new SSI algorithm for LPTV systems: Application to a hinged-bladed helicopter [PDF]
, 2014 Many systems such as turbo-generators, wind turbines and helicopters show intrinsic time-periodic behaviors. Usually, these structures are considered to be faithfully modeled as linear time-invariant (LTI).

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence
Advanced Functional Materials, EarlyView.Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...

Dissipation mechanisms identification of soft hollow particle-dampers in honeycomb structures for micro-vibrations environment [PDF]
, 2009 Particle dampers are enclosures partially filled with metallic or glass small spheres, attached to the vibrating structure. This paper deals with replacing hard classical particles by soft hollow ones to maximize damping and mass ratio. Hence, one aspect

Effective mass overshoot in single degree of freedom mechanical systems with a particle damper
, 2011 We study the response of a single degree of freedom mechanical system composed of a primary mass, M, a linear spring, a viscous damper and a particle damper. The particle damper consists in a prismatic enclosure of variable height that contains spherical

Application of Viscous Damper and Laminated Rubber Bearing Pads for Bridges in Seismic Regions
Metals, 2021 Normally, Laminated Rubber Bearing Pads (LRBPs) are directly placed between girders and piers and their role is to provide the bridge span with horizontal movement, and to transmit the gravity loads from the deck to the piers.
