关于部分铰接复合材料板的对称性

About symmetry in partially hinged composite plates

E. Berchio, A. Falocchi

摘要:

我们考虑一个部分铰接的复合材料板问题,我们调查定性性质,例如对称性和单调性,对应的密度最小化的第一个特征值的特征函数。通过显示操作员的格林函数的相关属性,并通过应用相对于一个固定的平面的偏振进行分析。作为一个副产品的研究,我们得到了一个Hopf型边界引理的运营商有自己的理论利益。这些陈述得到了数值结果的补充。

英文摘要:

We consider a partially hinged composite plate problem and we investigate qualitative properties, e.g. symmetry and monotonicity, of the eigenfunction corresponding to the density minimizing the first eigenvalue. The analysis is performed by showing related properties of the Green function of the operator and by applying polarization with respect to a fixed plane. As a by-product of the study, we obtain a Hopf type boundary lemma for the operator having its own theoretical interest. The statements are complemented by numerical results.
