The self-consistent model of Cherkaoui et al. [J. Eng. Mater. Technol. 116, 274-278 (1994)] is used to compute the effective material moduli of a viscoelastic material containing coated spherical inclusions. Losses are taken into account by introducing the frequency-dependent, complex shear modulus of the viscoelastic matrix. Mode conversion appears through the localization tensors that govern the micromechanical behavior near the inclusions. The results are compared with the scattering model and the data of Baird et al. [J. Acoust. Soc. Am. 105, 1527-1538 (1999)]. The two models are in good agreement. The advantage of the self-consistent model is that it is applicable to the case of nonspherical inclusions embedded in anisotropic materials.
切尔卡维等人[《工程材料与技术杂志》116, 274 - 278 (1994)]的自洽模型用于计算含有涂层球形夹杂的粘弹性材料的有效材料模量。通过引入粘弹性基体的频率相关复剪切模量来考虑损耗。模式转换通过控制夹杂附近微观力学行为的定位张量出现。将结果与散射模型以及贝尔德等人[《美国声学学会杂志》105, 1527 - 1538 (1999)]的数据进行了比较。这两种模型吻合良好。自洽模型的优点是它适用于嵌入各向异性材料中的非球形夹杂情况。
