Tree-like Structures as Hierarchical Coupled Oscillators,hes are modelled as pendula coupled to it. Conditions for the existence of modes localized in branches are determined in terms of the system parameters. This is then compared with the behaviour of the system performing large-amplitude vibration. It is found that certain localized modes exist when th

Asynchronous Modes of Beams on Elastic Media Subjected to Varying Normal Force: Continuous and Disc. For the latter ones, with three DOF (degrees of freedom), the classical linear analysis was used to discuss the vibration modes, whereas for the continuous model quasi-Bessel modes are proposed. In the 3-DOF model, pre-stressing is force-imposed, while in the continuous one it is applied through a
