PM4Sand and PM4Silt

PM4Sand: A Sand Plasticity Model for Earthquake Engineering Applications

  • The sand plasticity model, PM4Sand, by Boulanger and Ziotopoulou has been implemented as a dynamic link library (DLL) for use with the commercial program FLAC 8.0 (Itasca 2016). The manual and DLL are available here.
  • PM4Sand was developed for representing sands and other purely nonplastic granular soils in geotechnical earthquake engineering applications.

PM4Silt: A Silt Plasticity Model for Earthquake Engineering Applications

  • The silt plasticity model, PM4Silt, by Boulanger and Ziotopoulou has been implemented as a dynamic link library (DLL) for use with the commercial program FLAC 8.0 (Itasca 2016). The manual and DLL are available here.
  • PM4Silt was developed for representing plastic silts and clays that exhibit stress-history normalized behaviors in geotechnical earthquake engineering applications.
