The response of many materials of engineering interest to external loading is influenced by their microstructure. The components of such a microstructure may have different material properties, resulting in an enormous complexity in the response of a material. It is discussed how such dynamical response of advanced materials with an inner structure can be predicted numerically. A novel approach to resolve microstructural evolution effects and the load transfer between different constituents without computations at the finest scales is described. This approach is based on a generalization of the internal variable theory. Computation of high strain rate processes in real materials and structures with necessary efficiency and accuracy is another important task. Results of numerical simulations by means of a thermodynamically consistent algorithm are demonstrated on examples of wave propagation and martensitic front evolution.
