刚性夹杂的网络逼近均匀化

Homogenization of stiff inclusions through network approximation

David Gérard-Varet, Alexandre Girodroux-Lavigne

摘要:

本文研究了无限大电导率、随机稳定分布在均匀导电介质中的夹杂物的均匀化问题。Zhikov的一个经典结果表明,在粒子间距离的对数矩约束下,存在具有有限均匀电导率的有效模型。依靠网络近似的思想,我们提供了一个宽松的标准,确保同质化。文中还讨论了以前理论中未涉及的几个例子。

英文摘要:

We investigate the homogenization of inclusions of infinite conductivity, randomly stationary distributed inside a homogeneous conducting medium. A now classical result by Zhikov shows that, under a logarithmic moment bound on the inter-particle distance, an effective model with finite homogeneous conductivity exists. Relying on ideas from network approximation, we provide a relaxed criterion ensuring homogenization. Several examples not covered by the previous theory are discussed.
