Consistent control of energy dissipation in non-spherical particle contact via a structure-preserving formulation
Y. T. Feng
The control of energy dissipation in non-spherical particle contact remains an unresolved problem. Unlike spherical contact, where the interaction reduces to a one-dimensional norm…

Hidden Harmonic Structure, Universal Damping, and Stability Bounds in Nonlinear Contact Dynamics
Y. T. Feng
Nonlinear contact dynamics are widely regarded as intrinsically nonlinear systems whose behaviour depends strongly on geometry and impact conditions. Here we show that any one-dime…

Exact Phase-Space Analytical Solution for the Power-Law Damped Contact Oscillator
Y. T. Feng
We present an exact phase-space analytical treatment of the power-law damped contact oscillator governed by , valid for…
