“…Mohammad et al [6] had done experimental work and finite element study to determine Rayleigh damping coefficient α and β to be used in modal superposition technique in order to determine the damping ratio of other modes by using Determination of Rayleigh Damping Coefficient …numerically finite element and validating the result from experiment works. This method has been found very effective in the estimation of the transient response.…”

“…The concept of Rayleigh damping had been introduced by Load Rayleigh in order to solve numerically on the damping problem in a vibrating system and the concept is commonly used in solving finite element problem [6]. Rayleigh damping is the simplest and convenient way to determine numerically damping matric [C] under the following form:…”

“…For this reason, it is necessary to account for the structural damping rather than the artificial numerical one. A Rayleigh model [21] is chosen to describe the structural damping. Such damping is related to the damping matrix C, which can be represented as…”

“…In this study, the charge of the particles is fixed at 2.6 3 10 213 C, which is in the range for pharmaceutical excipient particles with the size of a few hundred microns, such as lactose. 26 Generally, Rayleigh damping, 27 which involves global damping and contact damping, are used in DEM simulations. In this analysis, only contact damping is considered.…”
