Damped Oscillations01:07

Damped Oscillations

In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Solid Mechanics

Background:

  • Monolayer two-dimensional (2D) materials exhibit high in-plane strength but low bending stiffness.
  • This susceptibility to instability impacts functionalities in 2D-based Micro/Nanoelectromechanical systems (M/NEMS), nanochannels, and proton transport membranes.

Purpose of the Study:

  • To quantitatively tune and investigate instability in suspended 2D materials.
  • To understand the mechanisms governing the dynamic wrinkling-splitting-smoothing process and recovery behaviors.

Main Methods:

  • Employing a novel push-to-shear strategy to induce and control instability.
  • Examining monolayer graphene and molybdenum disulfide (MoS2) under controlled mechanical stress.

Main Results:

  • Monolayer 2D materials exhibit stepwise instabilities with distinct recovery processes.
  • Instability and recovery paths are governed by material geometry, pretension, and elastic nonlinearity.
  • Local stress redistribution dictates varied instability and recovery behaviors.

Conclusions:

  • Tunable instability in suspended 2D materials allows for bending stiffness measurement.
  • This control opens avenues for programming nanoscale instability patterns and physical properties of atomically thin films.
