Micromechanical behavior of hierarchical materials (B04)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: from 2012 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 192346071

TP B4 addresses the micromechanical characterization and modelling of hierarchical nanoporous materials. An important aspect of the method development is the in-situ measurement of the evolution of the structure under deformation and its representation in form of mathematical descriptors. The structural description for each hierarchy level is an essential input for the modelling. Due to the high degree of complexity, the homogenized material response of a hierarchy level will be determined by a data driven approach and integrated in FEM beam models of the higher level via machine learning. The hierarchical model enables the prediction of the macroscopic deformation behavior and a tailored material design.
