Theoretical 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 not applicable.
      • 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.]
