A grazing bifurcation is the bifurcation that takes place as a mechanical oscillator system evolves smoothly from a nonimpacting to an impacting state. This Letter summarizes different types of universal behavior associated with grazing bifurcations by consideration of a simple sinusoidally forced system.
