# Hysteresis Damping

Hysteresis damping produces a force which is in phase with the velocity and proportional to the displacement, resulting in a linear equation of motion. Transmissibility at resonance is equal to 1/n where n is the loss factor of the material. Response characteristics are similar to viscous damping except that increasing frequency has no effect on a hysteresis damper.
