Mechanical joints can have a significant effect upon structural response, causing localized nonlinear stiffness and damping changes. As many structures are assemblies, in [...]

A new kind of seismic isolation system incorporating energy localization and a nonlinear restoring mechanism in one unit has been described in recent papers. Parametric s [...]

We study a nonlinear vibration isolation system capable of, (a) isolating its upper part (the ‘machine’) from periodic disturbances generated at its base; and (b) sim [...]

The phenomenon of energy pumping, in which vibratory energy is transferred irreversibly within a nonlinear, multi-degree-of-freedom system with the goal of reducing the t [...]

As part of a study of energy pumping in nonlinear multi-degree-of-freedom systems, a 2-DOF test rig comprising a linear, SDOF primary system weakly coupled to a nonlinear [...]
