  pre-consolidation pressure

The magnitude of load and that of pre-consolidation pressure as well as the loading rate has all significant influence on consolidation.

With the increasing of pre-consolidation pressure and loading rate, the rate of consolidation increases correspondingly.

On convexity, normality, pre-consolidation pressure, and singularities in modelling of granular materials

The issues of convexity, normality, pre- consolidation pressure, and singularities of yield surfaces are discussed in the context of granular materials and soil mechanics.

We then define the pre-consolidation pressure directly using the total volumetric strain.
