Two centrifuge tests on a quay wall and cantilevered retaining with saturated granular backfills were simulated using Finn-Byrne model. Capabilities of model in liquefaction analysis the evaluated. The subjected to horizontal acceleration time history vertical history. constitutive is linear elastic – perfectly plastic Hooke’s elasticity Mohr-coulomb criterion for yield surface assumed backfill...

We theoretically consider the problem of doping induced insulator to metal transition in bulk semiconductors by obtaining density as a function compensation, assuming that is an Anderson localization controlled Ioffe-Regel-Mott (IRM) criterion. calculate mean free path, on highly doped metallic side, arising from carrier scattering ionized dopants, which we model quenched random charged impurit...

A charged system search algorithm (CSS) is applied to the optimal cost design of water distribution networks. This algorithm is inspired by the Coulomb and Gauss’s laws of electrostatics in physics. The CSS utilizes a number of charged particles which influence each other based on their fitness values and their separation distances considering the governing law of Coulomb. The well-known benchm...

limitations in the design method used for the support systems of urban buildings make them vulnerable to damage by adjacent excavations. this paper examines a traditional system used to support excavation sites and adjacent buildings in which inclined struts are connected to the wall or foundation of the adjacent building. this method can be considered to be a type of shoring or underpinning. t...

The mechanical evolution of coal is evident when the pore pressure and surrounding stress alone influence it. However, response saturated under coupling effect confining needs further investigation. This study identifies behaviors burst tendency dry condition where simultaneously increase but keep constant difference by conducting a series triaxial compressions on high samples. results show tha...

This paper presents a three-dimensional slope stability limit equilibrium solution for translational planar failure modes. The proposed uses Bishop’s average skeleton stress combined with the Mohr–Coulomb criterion to describe soil strength evolution under unsaturated conditions while its formulation ensures natural and smooth transition from saturated regime vice versa. analytical is evaluated...

This paper presents the results of a numerical analysis impact rock mass geomechanical parameters on stability preparatory headings located within Legnica-Glogow Copper District. The shows calculations prepared for driven in two types with different strength and deformation parameters, which allow illustrating their influence safety mining performed underground copper ore mines. Numerical model...

A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...

Mudstone is a widely occurring type of rock in deep mining, and it crucial to understand its failure mechanisms strength characteristics under the interaction water high stress ensure stability deeply buried engineered mudstone. In this study, composition structure mudstone were obtained, triaxial tests conducted on five different contents four confining pressures using servo press. The variati...

This work presents a new damage criterion suitable for elastic, elastic-plastic/viscous or elastic-viscous-plastic materials involving rupture effects. Its derivation, made here within thermodynamic framework, follows previous scalar-valued mechanics approaches. Such approaches are appropriate to many geophysical problems quasi-brittle which there is no clear physical justification the level of...
