Abstract:
The Hertz and triangle models of soft impact, transition cross
grazing bifurcation boundaries, weak and strong regimes of
periodic impact motions, bifurcation diagrams, phase trajectories,
basins of attraction, Poincare maps, negative clearances - static
prestress of impacting bodies, transition into impactless motion.
