Rayleigh dissipation function
text:
In physics, the Rayleigh dissipation function, named after Lord Rayleigh, is a function used to handle the effects of velocity-proportional frictional forces in Lagrangian mechanics. It was first introduced by him in 1873. If the frictional force on a particle with velocity v → can be written as F → f = − k → ⋅ v →, the Rayleigh dissipation function can be defined for a system of N particles as
- R = 1 2 ∑ i = 1 N. This function represents half of the rate of energy dissipation of the system t
