This project concerns the study of mathematical problems in the theory of composite materials as modelled by partial differential equations. The search for optimal bounds on the effective moduli of composites leads to oscillatory or "chattering" solutions. The macroscopic effects of this oscillatory microstructure is of interest in determining the properties of composite materials. Related to this is the study of control of systems which have oscillatory coefficients.

本课题研究偏微分方程法模拟的复合材料理论中的数学问题。对复合材料有效模数的最优界的寻找导致了振荡解或“颤振”解。这种振荡微结构的宏观效应对确定复合材料的性能很有意义。与此相关的是对具有振荡系数的系统的控制的研究。
