Aspects of the microstructure characterisation, modeling and optimisation.

Seminar on Aspects of the microstructure characterisation, modeling and optimisation on the example of CFCs and MMCs from Dr. Romana Piat, Heisenberg Fellowship, Karlsruhe Institute of Technology

Development of new materials with desired properties is one the main objectives of Material Science. The process can be facilitated by utilization of the methods of numerical mechanics: Numerical microstructure optimization [1] using virtual material models [2-5].

The procedure of the microstructure optimization consists of the following steps:

• Microstructure characterization and identification of the so-called design variables and their bounds. (The design variables are dependent on the manufacturing process, e.g., orientation distribution of the inclusions, their shape etc.) [6-8];
• Development and experimental validation of the virtual material model [6, 7];
• Microstructure optimization using virtual material model approach with geometrical and loading restrictions imposed on the design variables’ bounds [8]. Feedback on the parameters of material manufacturing.

All these steps will be described in details for metal-ceramic and carbon/carbon composites
