开发了一种数值材料测试方法，用于表征具有异质微观结构的复合材料的等效或宏观机械和/或其他物理性能。所提出的方法用于测试各种宏观载荷模式下成分及其界面的各种异质微观结构和非线性材料行为。该方法中的数值材料测试旨在通过​​具有准静态隐式解方案的有限元方法结合周期性微观结构（即晶胞）的均质化理论来进行。
A method of numerical material testing is developed for characterizing equivalent or macroscopic mechanical and/or other physical properties of composite materials with heterogeneous microstructures. The proposed method is prepared for testing on a variety of heterogeneous microstructures and nonlinear material behavior of constituents and their interfaces under various patterns of macroscopic loading. The numerical material testing in this method is intended to be carried out by means of the finite element method with a quasi-static implicit solution scheme in conjunction with the homogenization theory for periodic microstructures, i.e., unit cells.
