摘要
针对Ｒｅｉｓｓｎｅｒ－Ｍｉｎｄｌｉｎ夹支板模型，给出了两个关于板厚一致收敛的稳定混合有限元逼近格式：其一，局部特征值摄动法；其二，残差ｂｕｂｂｌｅ－函数法。
In this note, we present two stabilized approximating schemes for the Reissner Mindelin plate with the convergence rate independent of the thickness by using mixed finite elements. The first method lies in the introducing the perturbation of the local eigenvalue in the mixed Ritz variational formulations, and the other one employing the residual bubbles.
