An interior penalty nonconforming finite element method for strain gradient elasticity
Xuehai Huang, Zheqian Tang
An interior penalty nonconforming finite element method is developed for a strain gradient elasticity (SGE) model in arbitrary dimensions, using an -nonconforming displacement…
Weakly Symmetric and Traceless Tangential-Normal Tensor Finite Elements: Application to the Brinkman Equations
Xuehai Huang, Xinyue Zhao
We develop a family of weakly symmetric and pointwise traceless tangential-normal tensor finite elements in arbitrary space dimension and for all polynomial orders. Symmetry is imp…
A Lowest-Order Robust Mixed Finite Element Method with a Third-Order Tensor Variable for Strain Gradient Elasticity
Xuehai Huang, Zheqian Tang
A lowest-order mixed finite element method is developed for the strain gradient elasticity (SGE) model in arbitrary dimensions. We take the physically meaningful third-order double…
Symmetric-Tensor Distributional Mixed Method for Fourth-Order Elliptic Singular Perturbation Problem
Xuehai Huang, Xinyue Zhao
A symmetric-tensor distributional mixed method for a fourth-order elliptic singular perturbation problem is developed in this paper. The moment variable is approximated by normal-n…
Finite element conformal complexes in three dimensions
Xuehai Huang
This paper extends the Bernstein-Gelfand-Gelfand (BGG) framework to the construction of finite element conformal Hessian complexes and conformal elasticity complexes in three dimen…
An Optimal and Robust Nonconforming Finite Element Method for the Strain Gradient Elasticity
Jianguo Huang, Xuehai Huang, Zheqian Tang
An optimal and robust low-order nonconforming finite element method is developed for the strain gradient elasticity (SGE) model in arbitrary dimensions. An -nonconforming quad…
Robust and Optimal Mixed Methods for a Fourth-Order Elliptic Singular Perturbation Problem
Xuehai Huang, Zheqian Tang
A series of robust and optimal mixed methods based on two mixed formulations of the fourth-order elliptic singular perturbation problem are developed in this paper. First, a mixed…
Antarctic Survey Telescope 3-3: Overview, System Performance and Preliminary Observations at Yaoan, Yunnan
Tianrui Sun, Xiaoyan Li, Lei Hu +17
The third Antarctic Survey Telescope array instrument at Dome A in Antarctica, the AST3-3 telescope, has been in commissioning from March 2021. We deployed AST3-3 at the Yaoan astr…
