Brief description This project aims to numerically simulate strain-softening-hardening in fine-grained soils. Fine-grained soils soften during deformation and harden as excess pore pressures dissipate. Models exist that allow strain-softening and hardening in finite element simulations, but suffer from mesh-dependency. Regularisation methods can alleviate mesh-dependency, but an appropriate characteristic length for the regularisation is needed and difficult to determine. This project will use image-based soil deformation measurement and aspects of the finite element method to determine appropriate regularisation techniques, characteristic lengths and constitutive relations. Reliably modelling strain-softening and hardening in finite element simulations is expected to reduce uncertainty in design and make civil infrastructure cheaper.
