Abstract
The radial mapping version of the bounding surface plasticity formulation is applied to isotropic cohesive soils. While some aspects of this constitutive model have appeared in the past, a number of important novel features, including closed form analytical relations for certain loadings and the complete analytical formulation, are presented here for the first time. Based on the new aspects a much improved predictive capability is obtained, as shown by successful comparison with experimental data under different loading conditions. The analytical formulation and the significance of the different model constants are carefully investigated in order to have a better understanding of the simulated material response as obtained by numerical methods.
