Materials Modelling Group (MMG)

Materials
Modelling Group
The Materials Modelling Group simulates metals and alloys using multiscale modelling techniques. These simulations are run on systems ranging from standard desktop PCs or on our own high-performance computer clusters.
Achievements include the most comprehensive computer simulation study to date of defect production and properties due to displacement cascades in metals and alloys
Why do we need to simulate engineering materials by computer?
Many processes that occur in materials cannot be investigated by other means and some properties are difficult to measure by experiment. For example some of the events we simulate occur in less that 1 pico second (1 million-millionth of a second).
Examples of Multiscale Modelling
Continuum scale:
Modelling the motion of dislocation lines when plastic yielding occurs under stress eg. in high temperature turbine blades.
Atomic Scale:
Modelling the interaction and motion of individual atoms in the crystal structure, eg. radiation damage in core structure components in nuclear power reactors. Atoms are displaced from their lattice sites in metals by fast neutrons created in the fission process, creating vacancies and interstitials.
What else can you find out?
We hope to establish an extended web site featuring much more on the Group's activities in the near future including a library of images and movies. Meanwhile a sample of our movies can be downloaded here (large files!)
