The objective of the research is to develop and to optimise a new numerical method, based on discrete Fourier transforms, which allows the prediction of macroscopic material properties of heterogeneous materials (composites) from a microstructural analysis. This analysis crucially relies on the accuracy, swiftness and efficiency of the numerical method employed for the computation of the local stresses and strains in a representative volume element (RVE) of the body. Suitable averaging of this information will then be used to predict macroscopic quantities of interest, such as the overall stiffness or uniaxial stress-strain curves of the composite. Features to be investigated within the scope of this work include: Influence of mechanical and thermal loading of the composite; non-linear (plastic) behaviour of the matrix and/or the heterogeneities; influence of the shape and geometrical arrangement of the second phase within the matrix; assessment of damage (cracks and voids); microstructural changes modelling of 2D and 3D- effects in composite materials; comparison of numerical results with experimental findings.
