Abstract

The ellipse assemblage model with imperfect interface has quite complex microstructure, that can be considered an extension of the circle assemblage model with imperfect interfaces. The paper introduces an approximate method for computing the effective conductivity of isotropic composites with imperfect interfaces in two-dimensional space. Based on the coated-ellipse assemblage model and the equivalent inclusion approximation, one can determine the effective thermal conductivity of the composites. The polarization approximation is given in an explicit form (PEK) and this method will be applied to calculate the effective conductivity of the composite with Kapitza thermal resistance model. The PEK result will have compared with the Fast Fourier Transform (FFT) simulation and Hashin-strikman bounds (HS).
考虑Kapitza热阻的椭圆包体模型有效电导率估算
带有非完美界面的椭圆组合模型具有非常复杂的微观结构,可以看作是带有非完美界面的圆形组合模型的延伸。本文介绍了二维空间中具有非完美界面的各向同性复合材料有效电导率的近似计算方法。基于包覆-椭圆组合模型和等效夹杂近似,可以确定复合材料的有效导热系数。极化近似以显式形式(PEK)给出,该方法将应用Kapitza热阻模型计算复合材料的有效电导率。PEK结果将与快速傅里叶变换(FFT)模拟和哈希-斯特里克曼边界(HS)进行比较。
