A Coupling Method of Mixed and Lagrange Finite Elements for Linear Elasticity Problem
Wei Chen, Jun Hu, Limin Ma +1
This paper proposes a finite element method that couples mixed and Lagrange finite elements to efficiently capture stress concentrations in elasticity problems. The method employs…
A direct finite element method for elliptic interface problems
Jun Hu, Limin Ma
In this paper, a direct finite element method is proposed for solving interface problems on unfitted meshes. This new method treats the two interface conditions as an $H^{\frac12}(…
Asymptotically exact a posteriori error estimates of eigenvalues by the Crouzeix-Raviart element and enriched Crouzeix-Raviart element
Jun Hu, Limin Ma
Two asymptotically exact a posteriori error estimates are proposed for eigenvalues by the nonconforming Crouzeix--Raviart and enriched Crouzeix-- Raviart elements. The main challen…
Asymptotic expansions of eigenvalues by both the Crouzeix-Raviart and enriched Crouzeix-Raviart elements
Jun Hu, Limin Ma
Asymptotic expansions are derived for eigenvalues produced by both the Crouzeix-Raviart element and the enriched Crouzeix--Raviart element. The expansions are optimal in the sense…
High accuracy methods for eigenvalues of elliptic operators by nonconforming elements
Jun Hu, Limin Ma
In this paper, three high-accuracy methods for eigenvalues of second order elliptic operators are proposed by using the nonconforming Crouzeix-Raviart(CR for short) element and the…
A Penalized Crouzeix-Raviart Element Method for Second Order Elliptic Eigenvalue Problems
Jun Hu, Limin Ma
In this paper we propose a penalized Crouzeix-Raviart element method for eigenvalue problems of second order elliptic operators. The key idea is to add a penalty term to tune the l…
