Zusammenfassung:The article considers the problems in the numerical stress-strain analysis of heterogeneous models of rock samples and biological tissues. The information about the geometric structure of such models is usually obtained using computed tomography (CT). The construction of the unstructured hexahedral meshes (based on CT scan data) is used to reduce the problem dimension. Examples of estimating the effective properties of a core sample and modeling a human lower jaw are given in the article.
