Finite element method for viscoelastic fractional derivative model
摘要
Abstract
The finite element scheme of viscoelastic structural dynamics with fractional derivative three el ements model constitutive relation was derived based on the analysis of the theory of the fractional deriv ative three elements model in this paper. And the numerical solution of the finite element equation was calculated using the numerical algorithm for the dynamics equation of the fractional derivative viscoelas ticity structure. Moreover, the efficiency of the finite element scheme was confirmed by the dynamic vis- coelastic response of two-dimensional asphalt pavement.关键词
