Abstract

The effective parameters of the composite materials with Gurtin–Murdoch ((G-M) interfaces are analyzed by standard boundary element method (BEM)-based equivalent inhomogeneity technique (EIT). The physical quantities all over the domain are first compared with the analytical and semi-analytical results to validate accuracy. The effective parameters are then obtained by the present numerical EIT. Since interactions have been considered, we believe our results are more accurate than traditional estimations, such as the generalized self-consistent model (GSCM). Due to the numerical treatment is performed to the present method is more flexible to simulate the effective parameters of clusters with complex geometries.

摘要

采用基于标准边界元法（BEM）的等效非均匀性技术（EIT）分析了具有Gurtin-Murdoch（（GM）界面的复合材料的有效参数。首先将整个域的物理量与解析和半-分析结果以验证准确性。然后通过当前数值 EIT 获得有效参数。由于考虑了相互作用，我们相信我们的结果比传统估计更准确，例如广义自洽模型 (GSCM)。对本方法进行了数值处理，更灵活地模拟了具有复杂几何形状的簇的有效参数。
