The experimental response of a broadband base-excited vibration isolator incorporating cubic damping
, 2013 Structural damping is often assumed to be viscous and linear which leads to comparatively straightforward vibration analysis. In the case of vibration isolation mounts this assumption of linearity is particularly questionable and one might want to know ...
