At Fraunhofer-Center HTL, significant modules for integrated computational materials engineering are already available (see Raether, F.; Seifert, G.: Integrated Computational Ceramics Engineering - an Approach to Radically Reduce Time-to-Market). Multiscale simulation concepts are available for all three of the relationships stated above. To the question how the manufacturing process influences the structure (relationship 1), models on different scales are used. On the microscale, for example, the microstructure development during sintering is simulated as a function of the process parameters, e.g. the temperature-time curve, and the resulting conditions for the greatest possible homogeneity of the ceramic are derived (see Raether, F.; Seifert, G.: Modeling Inherently Homogeneous Sintering Processes; Raether, F.; Seifert, G.; Ziebold, H.: Simulation of Sintering across Scales, Advanced Theory and Simulations). On the macro scale, FE models for debinding and sintering are available which are strictly based on precise in-situ measurement data from the heating process. With these models, the respective thermal process is optimized on the computer in such a way that the components achieve the desired final shape and density - reliably and crack-free with minimum time and energy requirement. For relationship 2, there is a microstructure property simulation (see Müller, Th.; Raether, F.: 3D modelling of ceramic composites and simulation of their electrical, thermal and elastic properties) available specially developed for ceramics, which has been extended in the meantime for the forecast of the material properties of ceramic fiber composite materials (CMC). For relationship 3, the computer-aided evaluation of application properties, the measured structures of surface or volume defects are evaluated at Fraunhofer-Center HTL aided by FE analyses with regard to their effects on the failure probability.
