Solid Mechanics Group is a small activity within the Department of Applied Mathematics and
Theoretical Physics but it is a part of a much larger activity in the
University, through participation in the Cambridge Centre for Micromechanics.
Within DAMTP, research in Solid
Mechanics is pursued by
Research interests include the following:
- Aspects of the
mathematical theory of homogenisation.
- Effects of non-locality
and scale, for problems in which the "homogenisation limit" is
- Propagation of waves in
randomly inhomogeneous media. Most studies to date have related to
linearly elastic media and further linear work is being pursued. The
effects of interconnected cracks on wave propagation and the
viscoelastic nature of the resulting material.
- Mechanics of fracture.
Problems include quasistatic and dynamic crack growth in elastic media
and crack stability to small perturbations of crack surface.
- Strain-gradient plasticity
and its origin in the interaction of dislocations.
- Rate-and-state description
of frictional sliding.
[Please note that Professor Willis reached the age for mandatory retirement
in 2007; his research continues but he is unable to take on new students.]
