Micromechanics and Materials Modelling

Overview

Understanding the behaviour of complex, hierarchically structured materials requires the combination of different modelling techniques. We use implicit and explicit finite element simulations of continua and microstructured alloys, ceramics and polymers, along with discrete dislocation dynamics and molecular dynamics simulations, to consider such phenomena as adiabatic shear bands, crystal slip and dislocation pile-up and interaction, twinning and phase transformations, in materials ranging from aerospace alloys to structural and functional ceramics to biological materials such as human dental tissues.
