 bubble函数
 bubble function
 To obey the rule of accuracy enhancement of combined hybrid method, stress modes which fit the completely energy compatible condition with bubble function are developed. Thus 5 new quadrilateral elements based on combined hybrid principle are obtained: CHDB1, CHD1, CHDB2, CHD2, CHD01.Compared with elements based on modified principle and interpolate rotation degrees of freedom independently, the five new elements use less variable and simpler in calculation. 根据组合杂交方法精度增强的要求,推导出与bubble函数完全能量协调的应力模式,从而得到五种基于组合杂交变分原理的新型四边形单元:CHDB1、CHD1、CHDB2、CHD2和CHD01单元。 和基于修正变分原理、独立插值转角自由度的其它有限元格式相比较,由于引入的场变量少,本文构造的系列单元计算相对简单。 短句来源

 bubble function
 Convergence of simplified and stabilized mixed element formats based on bubble function for the stokes problem Two simplified and stabilized mixed element formats for the Stokes problem are derived by bubble function, and their convergence, i. Motivated by this discovery, a new SDFEM is developed based on a special choice of the stabilization bubble function. It is found that, irrespective of the degree of mean and the rotational pressure interpolation, the linear triangle mesh, with or without central bubble function (incompatible mode), locks when both the constraints are enforced simultaneously. In order to satisfy the inf-sup condition we need to add to the usual piecewise quadratics a cubic bubble function. 更多

 We prove that for the new formulation one can use any stable mixed finite element for the Navier-Stokes equations with no-slip boundary condition provided suitable bubble functions on the boundary are added to the velocity space. We apply a mixed finite element approximation to the interface operator by iso triangular elements and prove the optimal error estimates in the presence of stabilizing bubble functions. Then we propose an asymptotically optimal compression technique for the related stiffness matrix (in the absence of bubble functions) providing a sparse factorized approximation to the Schur complement. In the presence of bubble functions, our method has the complexity arithmetical operations. The lower error bound is obtained by means of bubble functions and the corresponding anisotropic inverse inequalities. 更多
 This paper is devoted to the development of stabilized finite element methods by empolying local bubble functions for adveetive-diffusive models which has the form σu+a·(?)u-k△u =f. We show this methodology is stable independent of σ or Peclet-number and its globle optimal convergence order,from the problem with a=0 or σ=0. 本文针对形如σu+α·u-kΔu=f对流—扩散型的模型问题,发展耦合局部bubble-函数的有限元方法,我们就α=0和σ=0两种情形证明了方法的与“影响因素”σ和pedlet-数无关稳定性及全局最佳收敛阶。 For the Stokes problem, this paper establishes an equivalence among the bubble functions based stabilized finite element methods given by , GaLS stabilized methods and bubble functions enriching methods. 本文针对Ｓｔｏｋｅｓ－问题给出了［１２］发展的基于局部ｂｕｂｂｌｅ－函数稳定化有限元法与Ｇａｌｓ－稳定化有限元法，ｂｕｂｂｌｅ函数扩充元法的等价关系 Some locking free finite element methods for the cylindrical shell are studied. The authors obtain a nonstandard mixed finite element for which the discrete shear and the membrance tness are divided into two perts,and only one of both is projected into a lower order mute element,the authors use some Lagrange finite element spaces argumented by bubble function to approximate rotation and dispacement,and the error estimates are obtained uniformly in the shell thickness. 讨论了关于圆柱壳问题的Ｌｏｃｋｉｎｇ　Ｆｒｅｅ有限元方法，得到了一种非标准混合有限元．这种有限元将离散剪应力和离散膜应力分为两部分，但仅将其中的一部分投影到低阶有限元空间．作者用扩展了ｂｕｂｂｌｅ函数的拉格朗日多项式有限元法逼近转角和位移，得到了与壳厚度一致无关的误差估计．
