Second-Order Collocation-Based Mixed FEM for Flexoelectric Solids

Solids, 2023
Flexoelectricity is an electromechanical coupling between the electric field and the mechanical strain gradient, as well as between the mechanical strains and the electric field gradient, observed in all dielectric materials, including those with ...

Finite element models based on the approximation of discontinuous stress fields

Magazine of Civil Engineering, 2022
The paper develops the finite element method (FEM) in the form of the force method and in the mixed form for the calculation of structures. At present, the displacement-based finite element method is mainly used for engineering calculations. Stress-based

Explicit Multistep Mixed Finite Element Method for RLW Equation

Abstract and Applied Analysis, 2013
An explicit multistep mixed finite element method is proposed and discussed for regularized long wave (RLW) equation. The spatial direction is approximated by the mixed Galerkin method using mixed linear space finite elements, and the time direction is ...
