Background on PM4Sand
- The sand plasticity model PM4Sand was developed for geotechnical earthquake engineering applications by Professors Ross W. Boulanger (homepage) and Katerina Ziotopoulou (homepage) at the University of California at Davis.
- PM4Sand is a stress-ratio controlled, critical state compatible, bounding surface plasticity model for sand that has been implemented as a user-defined dynamic link library for use with the program FLAC by Itasca (homepage). The model was developed and implemented to approximate stress-strain responses of specific importance to geotechnical earthquake engineering and liquefaction problems.
