Modelling Stress-Strain Behaviour of Granular Soils
This paper presents a unified framework for constitutive modelling of the axial stress-volumetric strain behaviour of granular soils using an evolutionary polynomial regression technique. It is a data-driven method based on evolutionary computing, aimed to search for polynomial structures representing a system. A procedure is presented for construction of the model. The main advantage of the proposed model over conventional and neural network-based constitutive models is that it provides the optimum structure for the material constitutive model representation, as well as its parameters, directly from raw experimental (or field) data. It can learn nonlinear and complex material behavior without any prior assumptions on the constitutive relationship. The proposed algorithm provides a transparent relationship for the constitutive material model. Merits and advantages of the proposed technique are discussed in the paper.
