WebIn this formulation, the free energy determines the chemical equilibrium, while the dissipation functional D chem [R, ∂ t R] determines the reaction rate. It is worth mentioning that the variational principle ( 43 ) can be applied to other systems with non-quadratic dissipations, such as the systems studied in [ 58 , 59 ]. WebRayleigh damping is commonly used to provide a source of energy dissipation in analyses of structures responding to dynamic loads such as earthquake ground motions. In a finite element model, the Rayleigh damping matrix consists of a mass-proportional part and a stiffness-proportional part; the latter typically uses the initial linear stiffness
