Abstract
The paper desribes an energy‐based framework for a simple model
with two degrees‐of‐freedom that statically exhibits
bifurcations or limit‐points. Dynamically, the equivalent system may
respond with small amplitude motion (being dynamically stable) or
it may ‘escape’ and move to exhibit ‘large amplitude
motion’ (thus becoming dynamically unstable). The energy
framework is used to define bounds for these stable and unstable motions.
These bounds are used to provide a framework for a set of dynamic finite
element computations based on conventional finite element
techniques.
