The geotechnical literature is not exempt from oxymorons. For example, analytical solutions for interparticle contact clearly show that soils and all particulate materials are inherently non-linear -Hertz theoryand non-elastic -Mindlin’s theory (See Richart, Hall and Woods, 1970; Cascante and Santamarina, 1996). Yet, “linearelastic soil behavior” is a common expression. In most cases it refers ...

The paper presents classical and non-classical rheological schemes used to formulate constitutive models of the one-dimensional consolidation problem. authors paid special attention secondary effects in organic soils as well soil over-consolidation phenomenon. systems partial differential equations were formulated for every model solved numerically obtain settlement curves. Selected numerical r...

This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...

One of the newest of viscoelastic RANS turbulence models for drag reducing channel flow with polymer additives is studied in different flow and rheological properties. In this model, finitely extensible nonlinear elastic-Peterlin (FENE-P) constitutive model is used to describe the viscoelastic effect of polymer solution and turbulence model is developed in the k-ϵ-(ν^2 ) ̅-f framework. The geome...

many efforts have been made to model the the hot deformation (dynamic recrystallization) flow curves of different materials. phenomenological constitutive models, physical-based constitutive models and artificial neural network (ann) models are the main methods used for this purpose. however, there is no report on the modeling of warm deformation (dynamic spheroidization) flow curves of any kin...

A new constitutive model for the soil-water retention behaviour of unsaturated soils is proposed, able to reproduce main drying and wetting paths, cyclic its dependence on specific volume. The most significant aspect inclusion evolution, with volume, degree saturation when suction tends zero in paths considering presence entrapped air bubbles. used success drying/wetting cycles two Pearl clay s...

Heavy rainfall can lead to shallow slips in slopes that are initially in a state of partial water saturation. Multiphysics numerical modelling approaches taking into account the involved physical key processes in variably saturated soils during rainfall events could help in understanding the main slip mechanisms. The concerned processes are related to water flow through the solid matrix, soil w...

There is a growing demand for multi-story buildings residence and commercial purposes in coastal areas of Sindh, Pakistan. Such types soils are generally considered more compressible with high groundwater levels, which may cause lower shear strength higher settlement. The computation the settlement foundations requires use advanced constitutive models, not commonly used due to lack field or exp...
