Simple cantilever beam deflection - what is the simplest way to add a damper?

I am looking at a simple cantilever beam deflection: I understand the general expression for deflection/force would be: $y_s = \frac{Fx_s^3}{3EI}$ $F_p = \frac{3y_sEI}{x_s^3}$ If you were going to add viscous damping to the bending of the beam, would it be as simple as: $F = \frac{3y_sEI}{x_s^3} - cEIθ_t$ Where the equation for the angle of deflection is $θ = \frac{FL^2}{2EI}$ ? I have seen some suggestions that simple damping of cantelever beams is done by applying viscosity to the rate of angle change with respect to time. Is that generally correct? I have had some strange behaviors trying this so I'm not sure what the ideal simple solution is. Thanks for any help or answers/ideas for either question. It is appreciated.
