弹性问题的线性常数元稳定化方法
Stabilized linear-constant finite element method for elasticity problem
摘要
Abstract
The extensively used linear / constant element cannot be applied in solving elasticity problem because it dissatisfy the LBB condition.In this paper,we derive a stabilization scheme for elasticity problem based on the Bochev-Dohrmann-Gunzburger method by adding a consistent term and projection-type stabilization term,which can effectively bypass the inf-sup condition.The advantage a of our method lies in that it does not depend on the space dimension and require calculation of higher order derivatives or edge-based data structures.关键词
