A Review of the NorSand Constitutive Model’s Capabilities in Representing Common Loading Modes in Soil Mechanics
Publication: Geo-Congress 2024
ABSTRACT
The NorSand critical state constitutive model is a simple material model, which is popular in the analysis of the static liquefaction problem in tailings. In this paper, NorSand’s historical development and applications to geotechnical engineering practice are discussed, and single element simulations of NorSand are compared to laboratory test results to display to what extent the model is or is not capable of capturing the essential aspects of behavior under common loading modes and their boundary conditions within the framework of NorSand’s constitutive relations. To explore to what extent the material behavior can be captured, the critical state line for Toyoura Sand is adjusted to better capture the behavior of loose undrained tests on soil. NorSand is found to accurately predict drained triaxial material behavior and the behavior of dense soils, but struggle with accurately predicting the behavior of loose soils when zero total strain boundary conditions are applied.
