Granite residual soil is one of the most frequently encountered problem soils in tropical regions, whose mechanical behavior heavily depends on pattern variation mean effective stress (p’) during shearing, which can be classified into three categories: increasing-p’, constant-p’, and decreasing-p’. Unfortunately, so far, stress–strain strength characteristics granite have been studied mainly un...

The interface problem exists widely in building. Joints are interfaces of rock mass structures. To further study the influence morphological characteristics on shear mechanical properties sawtooth joints, this paper prepared rock-like materials based similarity principle and carried out direct tests joints. results showed that: (1) peak displacement joints first increases then decreases with in...

We investigate the mechanical properties of a layered material with interlayer friction. propose model that contains lateral elasticity and friction to obtain response function both in Fourier real spaces. By investigating how internal deformation is laterally induced due applied surface displacement, we find it transmitted into an apparent phase difference. also effective complex modulus show ...

This study aims to fully explore the influence of rock joint roughness in slope stability analysis an open mine. Therefore, based on least squares parameter estimation method, a generalized shear strength coupling roughness, which is used evaluate design, was established by matching formula reflecting relationship between coefficient and parameter. Firstly, verify calibrate model, physical dire...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...

The behaviour of a granular material is mainly dependent on its frictional properties, angle of internal friction, and cohesion, which, together with material density, are the key factors to be considered during the scaling procedure of analogue models. The frictional properties of a granular material are usually investigated by means of technical instruments such as a Hubbert-type apparatus an...

Hot ring rolling is a highly nonlinear, unsteady-state and asymmetry process which is affected by many parameters. The friction coefficient between the ring ,the driver roll and the idle roll is one of the problems, which has significant effect on the quality of final product. In this study, the effect of these two parameters on hot ring rolling was investigated based on a 3D coupled-thermo mec...

Soil shear strength is an important indicator of soil erosion sensitivity and the tillage performance cultivated layer. Measuring at a field scale difficult, time-consuming, costly. This study proposes new method to predict parameters (cohesion internal friction angle) by combining cone penetration test (CPT) data properties. A portable CPT measuring device with two pressure sensors was designe...

Affected by climatic conditions such as rainfall, evaporation and air temperature, most of the backfill soil is in an unsaturated state, decrease matric suction leads to failure retaining structure. In view this, this study takes vertical rigid wall with narrow research object, assuming that behind forms a circular arch considering interlayer shear stress; thus, analytical solution active earth...
