Influence of Intermediate Principal Stress on Plastic Flow

Transactions of the Japan Society of Mechanical Engineers, 1959
Let σ1, σ2 and σ3 (σ1>σ2>σ3) be the principal stresses, and σ3=0. Taking σ1 and σ2 as the axes, the criterion of plastic flow is not expressed by a smooth curve by the authors' theory, but a curve composed of two straight lines which intersect at σ1=4σ2 in the range between tension and pure shear. Experiments were carried out.

The Effect of Intermediate Principal Stress on Compressive Strength of Different Cement Content of Cement-Stabilized Macadam and Different Gradation of AC-13 Mixture

Applied Sciences, 2018
Since the effect of intermediate principal stress on the strength of pavement materials is not entirely clear so far, a proprietary true triaxial apparatus was developed to simulate the spatial status of principal stresses to conduct compressive strength

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

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 ...

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 ...

Dynamics of poroelastic filaments [PDF]

, 2004
We investigate the stability and geometrically non-linear dynamics of slender rods made of a linear isotropic poroelastic material. Dimensional reduction leads to the evolution equation for the shape of the poroelastica where, in addition to the usual ...
