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…

Lower order mixed elements for the linear elasticity problem in 2D and 3D
Jun Hu, Rui Ma, Yuanxun Sun
In this paper, we construct two lower order mixed elements for the linear elasticity problem in the Hellinger-Reissner formulation, one for the 2D problem and one for the 3D proble…

Mixed Variational Formulation of Coupled Plates
Jun Hu, Zhen Liu, Rui Ma +1
This paper proposes a mixed variational formulation for the problem of two coupled plates with a rigid {junction}. The proposed mixed {formulation} introduces {the union of} stress…
