PM4Silt

Description

The PM4Silt plasticity model was developed and implemented by Boulanger
and Ziotopoulou (2018) for representing low-plasticity silts and clays in geotechnical earthquake engineering applications. Model development emphasized approximating a range of undrained monotonic and cyclic loading responses of saturated low-plasticity silts and clays that exhibit stress-history normalized behaviors, as opposed to the responses of purely nonplastic silts and sands. PM4Silt is a stress-ratio and critical state controlled, bounding surface plasticity model that builds on the framework of the PM4Sand model.
