If the damping ratio is zero (ζ = 0), the machine is undamped. While, if it is smaller than one (ζ < 1), this means the vibration system is in underdamped mode. The critically damped case occurs when the damping ratio is one (ζ = 1) and the overdamped mode usually occurs if the damping ratio is higher than 1 (ζ > 1).
