Investigation of the effects of value and modeling approach of natural damping on nonlinear responses of low rise moment-resisting steel frames [PDF]
Journal of Structural and Construction Engineering, 2021 Nonlinear time history analysis is recognized as the most appropriate tool for assessing the real behaviour of structures during seismic excitations. Validity rate of obtained results from this analysis significantly depends to the modeling, details and ...

Nonlinear damping in graphene resonators [PDF]
Physical Review B, 2012 Based on a continuum mechanical model for single-layer graphene we propose and analyze a microscopic mechanism for dissipation in nanoelectromechanical graphene resonators. We find that coupling between flexural modes and in-plane phonons leads to linear and nonlinear damping of out-of-plane vibrations. By tuning external parameters such as bias and ac
