Investigation of the anisotropic mechanical response of layered shales
Energy Science & Engineering, 2023 Layered shales exist widely and are often encountered during shale gas development. However, the mechanical response of layered shales is significantly affected by the existence of beddings, resulting in the obvious anisotropy characteristics regarding ...

Formulation of cross-anisotropic failure criterion for soils
Water Science and Engineering, 2013 Inherently anisotropic soil fabric has a considerable influence on soil strength. To model this kind of inherent anisotropy, a three-dimensional anisotropic failure criterion was proposed, employing a scalar-valued anisotropic variable and a modified ...

Microstructure Based Failure Criterion For Ductile Materials
EPJ Web of Conferences, 2018 For ductile metals, the process of dynamic fracture occurs through nucleation, growth and coalescence of voids. The stress required to nucleate these voids is inferred from the velocimetry data (using the acoustic approach) and termed as the spall ...

Failure Criterion for Brick Masonry: A Micro-Mechanics Approach
Studia Geotechnica et Mechanica, 2015 The paper deals with the formulation of failure criterion for an in-plane loaded masonry. Using micro-mechanics approach the strength estimation for masonry microstructure with constituents obeying the Drucker-Prager criterion is determined numerically ...

Failure criterion for metallic glasses [PDF]
Philosophical Magazine, 2011 Metallic glasses exhibit not only multiple failure modes but also differences in ultimate strength, plastic strain to fracture and asymmetric deviation of failure angles from 45 degrees between tension and compression. The available failure theories cannot fully characterize these phenomena and the underlying physics has not been completely clarified ...

Uneven Stiffness Coal Seam: A New Structural Factor Prone to Coal Burst Based on Stiffness Theory
Applied Sciences, 2023 The development of stiffness theory is constrained by its contradiction with engineering experience. Several easily overlooked details of stiffness theory were clarified, and a qualitative evaluation formula for the risk of coal burst was provided.

Finite Element Simulation of Multi-Scale Bedding Fractures in Tight Sandstone Oil Reservoir
Energies, 2019 Multi-scale bedding fractures, i.e., km-scale regional bedding fractures and cm-scale lamina-induced fractures, have been the focus of unconventional oil and gas exploration and play an important role in resource exploration and drilling practice for ...
