Micromechanical analysis of kinematic hardening in natural clay [PDF]
, 2009 This paper presents a micromechanical analysis of the macroscopic behaviour of natural clay. A microstructural stress-strain model for clayey material has been developed which considers clay as a collection of clusters.

Effects of intermediate principal stress on creep closure of storage caverns in Maha Sarakham salt [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2017 True triaxial creep tests are performed to determine the effects of the intermediate principal stress on the timedependent behavior of the Maha Sarakham salt.

Acoustic Emission b Value Characteristics of Granite under True Triaxial Stress
Mathematics, 2022 The acoustic emission b value is an important and widely used parameter for the early prediction of rock fractures. In this study, five groups of true triaxial compression tests were conducted on granite specimens to analyze changes in b value during the

Ellipsoidal halo finders and implications for models of triaxial halo formation
, 2013 We describe an algorithm for identifying ellipsoidal haloes in numerical simulations, and quantify how the resulting estimates of halo mass and shape differ with respect to spherical halo finders.

Modified true triaxial Hoek-Brown criterion considering intermediate principal stress effect
Meitan kexue jishuIn order to improve the Hoek-Brown strength criterion not considering the influence of intermediate principal stress on rock strength, the evolutions of rock strength were investigated according to the results of the rock true triaxial compression test ...

Use of elastic stability analysis to explain the stress-dependent nature of soil strength [PDF]
, 2015 The peak and critical state strengths of sands are linearly related to the stress level, just as the frictional resistance to sliding along an interface is related to the normal force. The analogy with frictional sliding has led to the use of a ‘friction

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications
Advanced Materials, EarlyView.In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...
