title = "Limitations of Classic Constitutive Soil Models and Their Suitability to Represent Tailings Behaviour",
abstract = "Three constitutive models were used to numerically represent the behaviour of tailings using finite-element software FLAC 3D. The constitutive models Mohr-Coulomb, Modified Cam Clay and P2PSand were each calibrated for three unique tailings that characterised as predominantly sand, silt or clay. The results of advanced geotechnical laboratory testing, including suites of critical state triaxial testing and consolidation testing were used to calibrate the three constitutive models for the selected tailings. The suitability of each model to represent the key mechanical behaviours that govern tailings responses such as contractive/dilative behaviour, shear strength, pore-pressure response and soil hardening/softening behaviour was assessed. The study showed that constitutive models should be selected based on the material behaviour shown in advanced laboratory testing, rather than merely using the soil classification.",
