周期区域上的退化Robin型牵引问题

A degenerating Robin-type traction problem in a periodic domain

Matteo Dalla Riva, Gennady Mishuris, Paolo Musolino

摘要:

我们考虑一个线性弹性材料与周期性的一组空隙。在空洞的边界上,我们设置了一个罗宾型牵引条件。然后我们研究了当Robin条件变为纯牵引条件时位移解的渐近性质。也就是说,将有一个矩阵函数{ $b[k](\cdot)$,它解析地依赖于实参数$k$,并且对于$k=0$为零,我们将罗宾条件的狄利克雷样部分乘以$b[k](\cdot)$ }。我们表明,位移的解决方案可以写在$k$的幂级数收敛$k$在整个邻域的$0$。在我们的分析中,我们使用功能分析方法。

英文摘要:

We consider a linearly elastic material with a periodic set of voids. On the boundaries of the voids we set a Robin-type traction condition. Then we investigate the asymptotic behavior of the displacement solution as the Robin condition turns into a pure traction one. To wit, there will be a matrix function {$b[k](\cdot)$ that depends analytically on a real parameter $k$ and vanishes for $k=0$ and we multiply the Dirichlet-like part of the Robin condition by $b[k](\cdot)$}. We show that the displacement solution can be written in terms of power series of $k$ that converge for $k$ in a whole neighborhood of $0$. For our analysis we use the Functional Analytic Approach.
