Viscous Material

I am using viscous material to model a damper. When defining the viscous material, does anybody know what the damping tangent ($C) and tangent ($alpha) are? Thanks!

C and alpha are the parameters of viscous damper, the fomular

F= C* V^ alpha

F is damper force
V is damper velocity of the end of the damper deformation
alpha is called damper viscous index

based on these two parameters, the hysteresis loop is defined
