Constitutive Models for Soil and Rock in Numerical Analysis

Constitutive models play a vital role in numerical analysis for boundary value problems. Geomaterials exhibit highly nonlinear stress-strain behavior, shear dilatancy, and stress hysteresis when subjected to cyclic loading, to name a few. Depending upon the loading conditions, the soil mass could show either drained or undrained behavior. For example, consolidation settlement is a result of excess pore water pressure dissipation in a clayey soil deposit while soil liquefaction occurs due to the excess pore water pressure reaching its total stress in sandy soil deposit, both due to undrained loading. Rock, on the other hand, shows brittle stress-strain, shear dilatancy, and viscoelastic behaviors. Due to its complex fracture networks or discontinuities, rock mass behavior becomes extremely challenging to model. In this mini-symposium, we aim to solicit papers modeling above-mentioned behaviors in soil and rock within all frameworks of numerical analysis, including finite element method, finite difference method, discrete element method, and others. Applications of constitutive models in various engineering problems, including, not limited to, excavation, slope stability analysis, and soil liquefaction, are welcome. In particular, advanced models mimicking unsaturated soil behavior, thermal-hydraulic-mechanical-chemical (THMC) coupling problem, and large deformation are also welcome.
