Modelling of discontinuous problems (shocks, stress fronts, crush fronts, cracks, phase fronts, etc). "non-physical variables".

  1. Solidification and Melting with 1st-order Transport Equations and Non-physical Variables
  2. Stress Waves in Solids Using 2nd-order Transport Equations and Non-physical Variables
  3. Crushing of Foams Using 1st and 2nd Order Transport Equations and Non-physical Variables.

Brittle Materials: Graphite to concrete
Using the Aster code to design experiments, which could be investigated using our techniques, to validate the concrete models, particularly for aged materials. Manchester has experience in nuclear graphite (a semi-brittle material) ranging from modelling of material properties using micro-tomography to characterise microstructure, up to fracture mechanics (in-situ observation of crack nucleation and growth) with the aim of predicting effects of stress state and material condition on the variability of strength.

Crack-corrosion-fatigue
using code ASTER to understand the flow of pressurised water to and from a crack-tip in a corrosion-fatigue scenario. It is something we discussed sometime ago. The solid mechanics will be simulated first to calculate the moving boundary, and followed by computational fluid dynamics
