Abstract Scope |
Training machined learning models with microstructure-specific data on the material behavior makes it possible to use such data-oriented material models to describe the history-dependent mechanical response of a material during processing or even during its application of materials. Such a model can be considered as a digital material twin as it describes the specific material performance and can be used to adapt processing conditions on-line or to predict the remaining lifetime of a component. It is demonstrated that machine learning models can be successfully trained with mechanical data for polycrystals with different crystallographic textures. The required training data is obtained from micromechanical simulations based on the crystal plasticity method. The trained model accurately describes the texture-specific elastic-plastic material response under multiaxial loading conditions. In future work, the dynamics of microstructure evolution under thermal and mechanical loads will be included, to fully integrate the process-microstructure-property conditions in the digital material twin. |
