Summary
The modelling of the mechanical properties of a macrostructure, representative of the total structure, is demonstrated by the example of the unidirectional SiC fibre-reinforced SiC composite. The macrostructure is modelled from a suitable number of substructures, based on the properties of the individual phases and their interactions. The numerical access in the model is accomplished by means of the Finite Element Method (FEM). In numerical simulations, the statistically verified events of damage in the macrostructure are described. Finally the effect of important parameters like the fibre number, the fibre-matrix friction and the fibre Weibull parameter on the nonlinear behaviour of the macrostructure will be examined.
