Three-dimensional constitutive model for partially and fully saturated soils
, International Journal of Geomechanics, Vol: 5, Pages: 244-255, ISSN: 1532-3641Constitutive models for partially saturated soils often assume linear relationships for the variation of shear strength with suction and the shape of the partially saturated isotropic compression lines. It has been established, however, that for some soils these relationships are nonlinear. The shape of the isotropic compression line for partially saturated conditions is of particular importance, as it is directly related to the amount of potential collapse that a soil will experience upon wetting. When boundary value problems are analyzed, ignoring this nonlinearity can lead to very inaccurate predictions, and such models are of limited applicability. None of the current models have been demonstrated to predict collapse behavior in a satisfactory manner, especially at high values of stress and suction. In this paper, an exponential expression for partially saturated isotropic compression lines is implemented in an existing elasto-plastic framework for saturated and partially saturated soils. As a result, the constitutive relationship presented here is more flexible in its ability to model the collapse behavior of partially saturated soils over a larger range of suctions and stresses. A nonlinear expression is also adopted for the variation of shear strength with suction. In addition, a number of other refinements to the existing framework are introduced. Also presented in this paper are the results of a series of single element finite-element analyses. These results demonstrate the model's capabilities and added flexibility.

Lessons learned from full scale observations and the practical application of advanced testing and modeling
, Pages: 201-245Field observations from thirteen recent case histories from the UK and France are described which are used to assess an approach for predicting ground movements and soil-structure interaction. High quality site investigations, including very careful sampling and advanced testing are seen to be crucial to success. Providing there are adequate geotechnical data, the non-linear FE predictive approach advocated by the Authors is shown to be sufficient for most engineering purposes, considering typical project time scales. Factors that merit particular attention include: the geological model; sampling and testing quality; anisotropy and pressure dependency; a fully non-linear modelling approach; addressing behaviour from very small to large strains; the ‘structure’ of natural and artificial geomaterials; the possibility of brittle failure; three dimensional geometry and construction details; permeability and groundwater variations. It is shown, however, that the present approach does not capture some important long term effects of time, creep and ageing. Comments are also made on the use of such advanced techniques in combination with an ‘observational approach’, and on pos-sible avenues for further research and development.

Identification of the wind of Rayleigh-Benard convection
, PHYS FLUIDS, Vol: 17Using a symmetry-accounting ensemble-averaging method, we have identified the wind in unbounded Rayleigh–Bénard convection. This makes it possible to distinguish the wind from fluctuations and to identify dynamic features of each. We present some results from processing five independent three-dimensional direct numerical simulations of a =4 aspect-ratio domain with periodic side boundaries at Ra=107 and Pr=1. It is found that the wind boundary layer scales linearly very close to the wall and has a logarithmic region further away. Despite the still noticeable molecular effects, the identification of log scaling and significant velocity and temperature fluctuations well within the thermal boundary layer clearly indicate that the boundary layer cannot be classified as laminar.
