论文摘要
我们研究了线性弹性产生的最小二乘算子的光谱的近似值。我们考虑一个两场(应力/位移)和三场(应力/位移/涡度)配方;其他配方可以通过类似的技术进行分析。我们证明了先验估计值,并通过简单的二维数值实验确认了理论结果。
We study the approximation of the spectrum of least-squares operators arising from linear elasticity. We consider a two-field (stress/displacement) and a three-field (stress/displacement/vorticity) formulation; other formulations might be analyzed with similar techniques. We prove a priori estimates and we confirm the theoretical results with simple two-dimensional numerical experiments.
