Abstract

Barodesy is a new framework for constitutive modelling of soils. The actual version uses a constant value of the coefficient of earth pressure at rest K 0, which contradicts experimental findings. A straightforward modification is presented here to remove this shortcoming. The calibration of the material parameters remains as simple as in the original model.

Notes

  1. Proportional strain paths are characterised by constant ratios of the principal values ɛ1:ɛ2:ɛ3, that is, constant ratios of the principal values of the stretching D 1:D 2:D 3.
