THE CONSISTENCY CONDITIONS FOR DENSITY LIMITS OF HYPOPLASTIC CONSTITUTIVE LAW
The so called phase diagram of grain skeletons illustrates the range of possible void ratios between the pressure dependent bounds ei and et. It can be shown that in the framework of the actual hypoplastic model these bounds can be surpassed by particular deformation paths. This inconsistency is particularly acute in recently proposed FF.-calculations with density fluctuations. Here we propose a modification to render the formulation consistent.
