A new unified constitutive model for natural clay and sandTools AL-Sarri, Hussein A. H. (2019) A new unified constitutive model for natural clay and sand. PhD thesis, University of Nottingham.
AbstractOver the last decades, with the increase of constructions and buildings on soft soil with low bearing capacity, the need for a comprehensive tool to demonstrate the complicated response of soil under different loading conditions increases. To understand the behaviour of soil precisely, numerical analyses are used to predict the responses of geotechnical structures after incorporating more realistic constitutive models for soil behaviour. Despite the large number of modifications proposed to the standard Cam-clay model over the last three decades, these types of models still have not been very successful in modelling many of the characteristic features of heavily consolidated clays.
