摘要: 利用球座标系下的三重博里叶逆变换导出了均匀各向异性介质中具有横向各向同性性质一类介质的格林张量近似解,为研究属于这类介质的单向纤维增强复合材料和奥氏体钢等材料中声波的散射问题提供了理论基础。将所得的近似解与各向同性介质的情况作了比较,并进行了简单讨论。Abstract: Fourier transform method is used to obtain an approximate solution of Green's tensor to ho-mogeneous and transversely isotropic media like unidirectional fiber re-inforced composites and austenitic stainless steel materials in order to provide the theoretical basis for the scattering problems.A comparison to homogeneously isotropic media is presented and a brief discussion of the main features of the solution is given.
