Considering the energy dissipation caused by hydrate dissociation and granular
rearrangement at the micro level, a multiphase constitutive model of hydrate-bearing …

Deep rocks are typically under a true-triaxial stress state. The strength of deep rock is thus
dictated by both the direction and magnitude of principal stresses. The formulation of three …

This paper presents a micro-mechanical study on the characteristics of shear-induced
anisotropy in granular media. Based on three-dimensional Discrete Element Method (DEM) …

Quantitative assessment of the initial damage state of a structure and fatigue life prediction
on this basis, especially when it is sensitive to manufacturing quality, is crucial for both …

Planes of weakness like schistosity and foliation affect the strength and deformational
behaviors of rocks. In this paper, an attempt has been made to study the elastic and strength …

Fabric anisotropy has a significant influence on the mechanical behavior of sand. An
anisotropic plasticity model incorporating fabric evolution is formulated in this study …

A failure criterion fully considering the anisotropy and hydration of shale is essential for
shale formation stability evaluation. Thus, a novel failure criterion for hydration shale is …

Besides compressive or shear strength, the tensile strength is a key parameter for
determining the load bearing capacity of rocks, their deformation, damage and fracturing …

Soil is a cross anisotropic particulate medium with different strengths in various directions;
this is primarily due to its geological deposition process and the very fact that particles …

Foliated rocks are often encountered in underground engineering, and the spatial
orientation relationship between its foliation and in situ stress controls the stability of the …
