The linear stability of dilute particulate rings [PDF]

, 2006
Irregular structure in planetary rings is often attributed to the intrinsic instabilities of a homogeneous state undergoing Keplerian shear. Previously these have been analysed with simple hydrodynamic models. We instead employ a kinetic theory, in which

Simple approach for solution of the quasi-plane-strain problem in a circular tunnel in a strain-softening rock mass considering the out-of-plane stress effect

Underground Space, 2020
The out-of-plane stress is sometimes the major or intermediate principal stress in a circular tunnel opening. The influences of the out-of-plane stress and axial strain are often neglected in the stability analyses of tunnel excavation, which can induce ...

Stress induced polarization of immune-neuroendocrine phenotypes in Gallus gallus [PDF]

, 2017
Immune-neuroendocrine phenotypes (INPs) stand for population subgroups differing in immune-neuroendocrine interactions. While mammalian INPs have been characterized thoroughly in rats and humans, avian INPs were only recently described in Coturnix ...

Estimate of differential stress in the upper crust from variations in topography and strike along the San Andreas fault [PDF]

, 2005
The major bends of the San Andreas fault in California are associated with significant variations in the along-fault topography. The topography-induced perturbations in the intermediate principal stress may result in the rotation of the fault with ...

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

Analysis of the flowability of cohesive powders using Distinct Element Method [PDF]

, 2005
Computer simulations using Distinct Element Method (DEM) have been carried out to investigate the effect of cohesion on the flowability of polydisperse particulate systems. For this purpose, two assemblies with different values of surface energy and made

Study of intermediate principal stress effect on progressive damage and permeability characteristics of unloading sandstone

Meikuang Anquan
In order to investigate the effect of intermediate principal stress on the progressive damage and permeability characteristics of unloading sandstone, the unloading test was carried out under different intermediate principal stress conditions based on a ...

A Simple Solution and Dilatancy Characterization for a Circular Tunnel Excavated in the Nonlinear Strain-Softening and Nonlinear Dilatancy Rock Mass

Advances in Civil Engineering, 2023
Tunnel opening or excavation in the strain-softening rock masses primarily leads to initial stress release and rock deformation. The increasing plastic shear strain induces a nonlinear variation of dilatancy in rock masses. Therefore, tunnel stability is

FEM and Von Mises analysis on prosthetic crowns structural elements: evaluation of different applied materials [PDF]

, 2017
The aim of this paper is to underline the mechanical properties of dental single crown prosthodontics materials in order to differentiate the possibility of using each material for typical clinical condition and masticatory load.

Seepage Flow Properties of a Columnar Jointed Rock Mass in a True Triaxial Experiment

Geofluids, 2021
A columnar jointed rock mass is a type of rock mass with strong geometric anisotropy and high interface permeability. Its seepage characteristics pose new challenges to the construction and maintenance of the Baihetan Hydropower Station on the Jinsha ...
