Multi-scale modelling of silicon carbide reinforced titanium MMCs: Application to advanced compressor design

This paper presents a multiscale approach developed to predict the non-linear behaviour of a unidirectional metal matrix composite. First, the pertinent scales are determined using experimental and numerical results. A macroscopic model, based on micromechanics, coupling viscoplasticity, damage and thermal effects is developed. One of the great advantages of such an approach is the possibility of varying some geometrical (fibre volume fraction) or material (viscoplastic law) parameters without having to re-identify the whole model. Finally, this model is used to simulate a real industrial structure.
