Fuzzy-based parameter uncertainty in an elastoplastic model for clay
Fuzzy-based parameter uncertainty in an elastoplastic model for clay
In this paper, we try to analyse uncertainty in constitutive modelling of clays. The main objective is to analyse parameter uncertainty in an elastoplastic model for clay by considering a fuzzy-based distribution of the elastic bulk modulus and shear modulus . Interval arithmetic is fundamental in the fuzzy-based approach, as it allows taking into consideration the uncertainty that arises from and and thus in the matrix of material properties D. A Mohr-Coulomb soil model is considered in the analysis. Fuzzy sets are well suited for representing vague and scarce data encountered in soil tests. Histograms of probabilities can be used to construct fuzzy sets. Simulations are run based on existing data, and comparisons with available results are highlighted. The effect of fuzzy-based parameter uncertainty is quantified using the Hartley-like measure.
