Abstract : The report discusses some of the more complex Soil Models available for input to advanced computer codes. It provides a brief overview of the impact of recent computer code advances upon development within the field of soil mechanics. Two different types of models are discussed: (1) Variable Moduli Models based upon incremental elasticity (2) Elastic-plastic models in which plastic yielding conditions are superimposed upon elastic behavior. The difficulties involved in using experimental data to fit a soil model are considered briefly and the major requirements for acceptable soil constitutive model are presented. The report concludes that the most fruitful avenue of pursuit for future soil-structure interaction studies will involve a versatile form of the variable moduli model. (Author)
