Constitutive relations for two-dimensional deformations of cohesionless granular materials are considered. The granular materials are assumed to be isotropic and rate-independent. One of the current trends in modelling the behaviour of granular materials is to study constitutive relations of the hypo-elastic The general hypo-elastic constitutive relation, originally proposed by Tr~esdell ,~ is ...

By the year 2035 it is estimated that Delhi and Mumbai will become two of most populous cities around globe. The massive population growth rate has led to rise land scarcity, urbanization, industrialization developments for rapid transit systems have made accordingly. Modern comprise Metro rails subways etc., increase underground-construction activities. Nowadays, tunnel-construction process he...

Abstract. The flowing of powders brings a new challenging and interesting problem to the CFD community: at very high concentrations and low rate-of-strain, grains are in permanent contact, rolling on each other. Therefore a frictional stress model must be taken into account. This can be done using plasticity and similar theories in which the granular material behaviour is assumed to be independ...

Introduction: Embankments are constructed in many places for transportation purposes such as railways and roads. The stability of slopes embankments has always been a concern, especially cohesionless soils. There methods to increase the safety factor soil using geogrids, geocells, concrete piles, so on. conventional material used stabilize huge impact on environment. Nowadays, researchers natur...

Abstract The present work deals with assessment of earthquake-induced displacement the base restrained retaining walls (RW’s). A detailed and rigorous finite element (FE) investigation has been carried out following shaking table experiments on a scaled-down RW model. FE simulations were performed by conducting several nonlinear time history analyses two-dimensional (2D) plane strain model prot...

This article examines the performance of Minimax Probability Machine Regression (MPMR) for prediction of settlement(s) of shallow foundation on cohesionless soil. MPMR maximizes the minimum probability that future predicted outputs of the regression model will be within some bound of the true regression function. Width of footing (B), net applied pressure (q), average Standard Penetration Test ...
