The HTL already has developed essential components for integrated, computer-aided material development (publication: Integrated Computational Ceramics Engineering). Concepts for multiscale simulation are available for all three of the aforementioned relationships. To investigate how the production process influences the structure (relationship 1), models are used on different scales: on the microscale, for example, the microstructure development during sintering is simulated depending on process parameters such as the temperature-time curve. Insights are derived from this about the conditions for achieving maximum homogeneity of the ceramics (publications: Modeling Inherently Homogeneous Sintering Processes and Simulation of Sintering). On the macroscale, FE models are available for debinding (publication: Optimization of Debinding Using Experiment-Based Computational Concepts) and sintering, based strictly on precise in-situ measurement data from the thermal processes. With these models, the respective thermal process is optimized on the computer so that the components achieve the desired final shape and density reliably and without cracks with minimal time and energy expenditure.
A microstructure-property simulation specifically developed for ceramics (publication: Using a novel microstructure generator to calculate macroscopic properties of multi-phase non-oxide ceramics in comparison to experiments) is available for relationship 2. It is suitable not only for pure ceramics but also for predicting the material properties of metal-ceramic composites (MMC) and ceramic fiber composites (CMC) (publication: 3D modelling of ceramic composites).
Regarding relationship 3, the computer-aided assessment of application properties, at the HTL, measured structures of surface or volume defects are evaluated using FE analyses for their impact on the probability of fracture.
