Multi-scale modelling of solids is an area of increasing interest within the applied and computational mechanics community. Multi-scale concepts allow the development of new models to describe the constitutive behaviour of solids by including information at two or more physical scales. Development of models of this type, in particular with the use of computational homogenisation methods based on Finite Element procedures, is currently under way. Computational multi-scale techniques lead to formidable tasks from the computing point of view. Therefore, the overall efficiency of the multi-scale framework needs to be optmised to allow its use in the solution of practical problems. In this context, computational techniques stemming from the expertise of this research group are under development, which so far have produced substantial reductions in computing time. Further developments are foreseen in the near future.
