چکیده
In this study, we mainly employ a proper orthogonal decomposition (POD) to lower the dimension for unknown Crank–Nicolson finite element (FE) (CNFE) solution coefficient vectors of viscoelastic wave (VW) equation so as build reduced-dimension recursive CNFE (RDRCNFE) algorithm, adopt matrix analysis analyze stability together with errors RDRCNFE solutions, and utilize some numerical experimentations verify effectiveness algorithm.

An optimized finite element extrapolating method for 2D viscoelastic wave equation
In this study, we first present a classical finite element (FE) method for a two-dimensional (2D) viscoelastic wave equation and analyze the existence, stability, and convergence of the FE solutions. Then we establish an optimized FE extrapolating (OFEE) method based on a proper orthogonal decomposition (POD) method for the 2D viscoelastic wave equation and analyze the existence, stability, and...
متن کاملA space-time finite element method for the wave equation*
where n is a bounded open domain in R d with d ffi 1, 2 and T > 0. We have restricted our attention to a specific problem entirely to keep the presentation simple. Our results apply to considerably more general second-order hyperbolic problems. Typically an approximation to (1) is found by first discretizing in space to obtain the semidiscrete problem that consists of ordinary differential equa...
متن کاملFinite Element Heterogeneous Multiscale Method for the Wave Equation
A new finite element heterogeneous multiscale method (FE-HMM) is proposed for the numerical solution of the wave equation over long times in a rapidly varying medium. Our new FE-HMM-L method not only captures the short-time behavior of the wave field, well described by classical homogenization theory, but also more subtle long-time dispersive effects, both at a computational cost independent of...
متن کاملDiscontinuous Galerkin Finite Element Method for the Wave Equation
The symmetric interior penalty discontinuous Galerkin finite element method is presented for the numerical discretization of the second-order wave equation. The resulting stiffness matrix is symmetric positive definite and the mass matrix is essentially diagonal; hence, the method is inherently parallel and leads to fully explicit time integration when coupled with an explicit timestepping sche...
متن کاملA mixed finite element approach for viscoelastic wave propagation
In this paper, we are interested in the modeling of wave propagation in viscoelastic media. We present a family of models which generalize the Zener’s model. We achieve its mathematical analysis: existence and uniqueness of solutions, energy decay and propagation with finite speed. For the numerical resolution, we extend a mixed finite element method proposed in [8]. This method combines mass l...
