Non-Holonomic Stability Aspects of Piecewise-Holonomic Systems (PDF)

Reports on Mathematical Physics, V. 42, No 1/2, P. 91-100, 1998

This paper demonstrates by means of a simple example that systems that are piecewise holonomic but have intermittent contact inherit some of the stability properties of non-holonomic systems.

This paper discusses the dynamics and stability of a piecewise holonomic mechanical system as a function of mass distribution and geometry. It further explores the ideas presented in the above paper.
