The direct application of the Hoek–Brown failure criterion to practical slope engineering is still an urgent problem. geometries and earthquake effect need be considered in determination linear Mohr–Coulomb (MC) strength parameters from criteria for stability analysis. This study adopted tangential method construct a three-dimensional (3D) rotational mechanism using homogeneous rock slopes unde...

Background: This study presents a numerical solution for determining the limiting uniform normal pressure acting horizontally behind cohesive-frictional backfill material in deep contiguous piled wall. At this pressure, soil tends to flow out gaps between series of vertical piles placed at certain horizontal spacing. Methods: The lower and upper bound plane strain finite element limit analysis ...

Abstract Study of mechanical properties rock under hydro-mechanical coupling. The MTS815 mechanics system is used to perform triaxial compression tests water-saturated sandstones different confining pressures and pore water pressures. results show that the peak deviation stress its corresponding axial strain, residual stress, initial dilation deformation modulus sandstone are related pressure p...

Realistic mesh-independent simulations of localization in a macroscopically homogenous material must incorporate (explicitly or statistically) length and orientation scales that reflect microscale inhomogeneities. Weibull statistics (or similar approaches) have long been used to allow for uncertainty in the size and spatial locations of microcracks, but little work has been done to determine th...

Many researchers have used different failure criteria in published solder joint reliability studies. Since the reported timeto-failure would be different if different failure criteria were used, it would be difficult to compare the reported reliability life of solder joints from one study to another. The purpose of this study is to evaluate the effect of failure criteria on the reported thermal...

Abstract. We discuss the advantages and results of using a mixing-length, compressible model to account for shear banding behaviour in granular flow. We formulate a general approach based on two function of the solid fraction to be determined. Studying the vertical chute flow, we show that shear band thickness is always independent from flowrate in the quasistatic limit, for Coulomb wall bounda...

The present contribution deals with the numerical modeling of railway track-supporting systems-using coupled finite-infinite elements-to represent the near and distant field stress distribution, and also employing a thin layer interface element to account for the interfacial behavior between sleepers and ballast. To simulate the relative debonding, slipping and crushing at the contact area betw...
