• Mixed Hardening Models for Frictional Soils 

      Søreide, Ole Kristian (Dr. ingeniøravhandling, 0809-103X; 2003:21, Doctoral thesis, 2003)
      A new material model mainly for frictional soil is developed and implemented in a finite element program. The model is applied to simulate a deep excavation with a supporting tie back wall. The model is based on ...
