Damping in Finite Element Analysis | PrePoMax

Damping is the loss of energy in a dynamic system by dissipation.
Characteristics for Damping:
- Damping Ratio (ζ)
- Rayleigh damping: mass proportional α damping and stiffness proportional β damping.
Methods for calculate the damping ration
- Logarithmic Decrement Methode
- Half Power Bandwidth Method

    It is necessary to make a reservation that this, at least for metals, is Rayleigh friction, which is not physical.
