A Bounding Surface Model for Granular Soils Subject to Cyclic Loading

摘要

A constitutive model is presented for the stress-strain behaviour of sand subject to monotonic and cyclic loadings. The model is formulated using bounding surface theory within a critical state framework. A single set of material parameters is introduced for the complete constitutive modelling. Essential features of the model are validated against several experimental data from the literature. Both drained as well as undrained loading conditions are considered.
