The coupling of mixed and primal finite element methods for the coupled body-plate problem
Jun Hu, Zhen Liu, Rui Ma
This paper considers the coupled problem of a three-dimensional elastic body and a two-dimensional plate, which are rigidly connected at their interface. The plate consists of a pl…
Optimality of adaptive mixed finite element methods for the Kirchhoff-Love plate bending problem
Jun Hu, Rui Ma, Min Zhang
This paper presents a reliable and efficient residual-based a posteriori error analysis for the symmetric mixed finite element method for…
A nodal basis for the - finite elements on 5D simplex grids
Jun Hu, Shangyou Zhang
We construct a nodal basis for the 5-dimensional finite element space of polynomial degree on simplex grids, where the finite element functions are on the 6 4D-sim…
Partial relaxation of C^0 vertex continuity of stresses of conforming mixed finite elements for the elasticity problem
Jun Hu, Rui Ma
A conforming triangular mixed element recently proposed by Hu and Zhang for linear elasticity is extended by rearranging the global degrees of freedom. More precisely, adaptive mes…
