Roll damping
Roll damping is the dissipation of energy opposing a ship's side-to-side rolling motion; roll is the largest and least damped ship motion, so it is central to predicting behavior in waves.
Roll forming
Roll forming is a continuous metal forming process in which flat sheet or strip is progressively bent into a constant cross-sectional profile by passing through successive pairs of profiled rolls.
