Strength reduction finite element method (SRFEM) has been widely used to analyze the slope stability. Strength Reduction Factor (SRF) is yielded as the slope Factor Of Safety (FOS) when a running-though shear failure zone comes into being, in which the Plastic Element EQuivalent strain (PEEQ) is employed as the judgment of shear failure initiation in this paper. Moreover, the filed variable is ...

This study investigates the shear capacity of aluminum alloy honeycomb sandwich plates connected by high-strength, ordinary, or self-tapping bolts. For that purpose, experimental tests and finite elements are carried out. The failure of a high-strength bolt connector is driven by bending deformations developed in the bolt that deform connection plate and pad openings. In the case of ordinary bo...

The dynamic tensile failure of rock is a main mode in deep underground engineering projects. microscopic mechanism analysis this plays key role disaster warning. Moment tensor inversion very well-known method used to analyze mechanisms. However, an acoustic emission (AE) event cannot be accurately distinguished experiments at the laboratory scale, because there are hundreds AE events generated ...

Toppling failure is one of the most common modes of failure of rock slopes in layered rock strata. Flexural toppling is one of the well-known modes of the failure. This type of failure occurs due to bending stress. In this article, a brief yet comprehensive review of toppling failure is presented. Firstly, the conditions and general mechanism of the failure are described. Then, experimental, th...

Integrated non-destructive testing (NDT) method consisting of acoustic emission (AE) and digital image correlation (DIC) was used to monitor evaluate the load-behaviour shear-critical reinforced concrete beams subjected corrosion. Measurement data in forms mechanical load, deflection, surface strain AE signals were processed collectively analysed facilitate interpretation damage development cha...

Taking the “11.28” rockburst occurred in Jinping II Hydropower Station as engineering background, evolution mechanism of structure-type was studied detail based on particle flow code. The results indicate that failure includes a tensile fracture induced by tangential compressive stress and shear caused due to overburdened loadings slip structural plane. In addition, it is found differences betw...

This paper reports on an experimental and analytical investigation conducted into efficacy of the scraping shear-test method in estimating the shearing adhesive strength of a thermally sprayed coating. It was found that the critical average shear stress, the apparent failure strength of WC-Co thermal spray coating, depends on both the dimensions of the test piece and the loading position around...

We investigate the mechanical responses of dense granular materials, using a direct shear box combined with simultaneous acoustic measurements. Measured shear wave speeds evidence the structural change of the material under shear, from the jammed state to the flowing state. There is a clear acoustic signature when the shear band is formed. Subjected to cyclic shear, both shear stress and wave s...

the effects of cementation and the physical properties of grains on the shear behavior of grouted sands are investigated in this paper. the consolidated-undrained triaxial shear behavior of three grouted carbonate sands with different physical properties, including particle size distribution, particle shape and void ratio, was studied. two sands were obtained from the north shores of the persia...

This paper focuses on the application of a continuum-based method in the Shear Strength Reduction (SSR) analysis of the stability of jointed rock slopes. In order to take into account the jointed nature of the material, the Finite Element Method (FEM) is formulated based on Cosserat theory. Also, it is assumed that failure of the equivalent material can result from failure of the joints, failur...
