Multimode cable vibration control using a viscous‐shear damper: Case studies on the Sutong Bridge
Structural Control & Health Monitoring, 2020 This study investigates multimode damping effects of a long cable attached with a viscous‐shear damper (VSD). A typical VSD comprises a casing box containing viscous medium and shearing plates with parts submerged in the medium.

Graphene nanoribbon as an elastic damper [PDF]
Nanotechnology, 2018 Heterostructures composed of dissimilar two-dimensional nanomaterials can have nontrivial physical and mechanical properties promising for many applications. Interestingly, in some cases, it is possible to create heterostructures composed of weakly and strongly stretched domains with the same chemical composition, as it has been demonstrated for some ...
