Non-linear mode coupling in symmetrically kinked bars

Legge, K. A.; Fletcher, Neville H.

Description

A theoretical and experimental study of energy transfer between the vibrational modes of a symmetrically kinked bar with clamped ends is described. Two non-linear mechanisms responsible for energy transfer from one mode to another at twice the frequency are identified. The first arises from the interaction between shear and tensional forces at the kink and the second from unbalanced moments across the kink. In the system studied, the first of these mechanisms is dominant. A further related...[Show more]
