Overview

Randomized trial demonstrates equilibrium and stability of coupled nonlinear systems, indicating a new analytical approach.

Key Points

  • The aim is to develop a framework for predicting equilibrium states and stability in coupled nonlinear systems.
  • Introduced a static framework with a parametric space to visualize element-level equilibria.
  • Applied a continuation strategy combined with local stability assessment to trace stable and unstable equilibria.
  • Validated the method experimentally in the mechanical domain using nonlinear-spring and inflatable systems.
  • Achieved quantitative agreement between predictions and experimental measurements.
  • Successfully traced stable and unstable equilibria, including isolated isolas that standard methods could not access.
