Mechanical Model of a Hybrid Non-linear Viscoelastic Material Damping Device With Its Verifications
Frontiers in Materials, 2019 This paper proposes a new viscoelastic (VE) material damping device with hybrid non-linear properties. Compared with traditional linear material dampers, the new non-linear VE material damping device is characterized by its better energy dissipation and ...

Viscoelastic High-Damping Materials [PDF]
The Journal of the Acoustical Society of America, 1963 An intensive investigation of polymers, polymer systems, and fillers was conducted that provided a material that effectively damps steel-plating up to 2 in. thick. The damping material exhibited greater than 3% critical damping over two decades of frequency and a 25°C temperature range, at a 13 plate-weight application. At an optimized temperature, the

Adhesive Contact Mechanics of Viscoelastic Materials
International Journal of Solids and Structures, 2023 In this study, we propose a theory of rough adhesive contact of viscoelastic materials in steady-state sliding. By exploiting a boundary formulation based on Green function approach, the unknown contact domain is calculated by enforcing the local energy balance at the contact edge, thus considering also the non-conservative work of internal stresses ...

Advanced Functional Materials, EarlyView.Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Electroactive Liquid Crystal Elastomers as Soft Actuators
Advanced Functional Materials, EarlyView.Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Design and Analysis of a 1D Actively Stabilized System with Viscoelastic Damping Support
Actuators, 2019 Passively magnetically stabilized degrees of freedom yield the benefit of reduced complexity and therefore costs. However, the application of passive magnetic bearings (PMBs) also features some drawbacks.
