Abstract Seismic anisotropy of polycrystalline materials depends on the characteristics of microcracks as well as the crystallographic orientations of minerals. Here, we present a MATLAB-based software, AnisEulerSC (Anisotropy from Euler angles using Self-Consistent approximation), for modeling the anisotropic seismic properties of a polycrystalline aggregate with microcracks using the self-consistent approximation. In this program, several commands of MTEX (a MATLAB toolbox for texture analysis) are utilized to analyze constituent components of a rock sample based on experimental measurement data (e.g., electron backscatter diffraction) and to calculate and visualize seismic wave velocities and polarizations. We provide several examples of SC modeling to explore the effects of grain shapes on a polycrystalline aggregate and the effects of crack shapes and orientations on the anisotropic seismic properties of a polycrystalline aggregate.

AnisEulerSC：结合 MTEX​​ 的 MATLAB 程序，用于使用自洽近似对具有微裂纹的多晶骨料的各向异性地震特性进行建模

摘要 多晶材料的地震各向异性取决于微裂纹的特征以及矿物的结晶取向。在这里，我们提出了一个基于 MATLAB 的软件 AnisEulerSC（使用自洽近似的欧拉角各向异性），用于使用自洽近似对带有微裂纹的多晶骨料的各向异性地震特性进行建模。在该程序中，利用 MTEX​​（用于纹理分析的 MATLAB 工具箱）的几个命令，根据实验测量数据（例如，电子背散射衍射）分析岩石样品的组成成分，并计算和可视化地震波速度和极化。
