Abstract
In this paper, by introducing two meaningful auxiliary variables, a
mixed finite volume element scheme for the time-fractional damping beam
vibration equation is established. The scheme can keep the local
conservation of physical quantity and reduce the computational cost.
Then the stability and convergence of the scheme are analyzed, and
numerical examples show its effectiveness. In the end, we test the value
of different sets of parameters to observe the influence of damping
coefficient and order of fractional derivative on the model. The results
of this paper can be used for modeling the damping of the viscoelastic
structures.
