Crisis-induced intermittency in a parametrically driven, gravitationally buckled, magnetoelastic amorphous ribbon experiment (invited)

Transversely annealed amorphous metallic glass ribbons exhibit extremely large magnetoelastic coupling. Consequently, the Young’s modulus of this material can be altered by a factor of 10 with the application of a small magnetic field. This effect is exploited to drive a vertically aligned ribbon, clamped at the bottom and free at the end, by buckling the ribbon gravitationally. Periodic, quasiperiodic, intermittent, and chaotic behavior are observed experimentally. A model for the system is also presented.
