Damping coefficient of stainless steel
Web11 rows · Viscous Damping Ratio ζ (as percentages of critical damping) Metals (in elastic range) less than ... WebThe viscous damping coefficient is the coefficient c in the formula. F = − c v. where F is the damping force and v is the velocity. c depends on what causes the damping. If it is a spring in air, then it is likely to be proportional both to the viscosity of the air and to the relevant area of the the spring leading to the damping.
