Abstract Scope |
This work will present the high-throughput micromechanical simulation workflow and demonstrate its capability to produce data for developing a machine learning model for deriving microstructure-property relationships. The first application example aims to predict anisotropic mechanical behavior from a given crystallographic texture. We will generate micromechanical models with different crystallographic texture information, couple them with a phenomenological crystal plasticity model, and simulate them under various loading conditions to characterize anisotropic mechanical behavior virtually. We will also propose a metadata schema for describing micromechanical simulations, which assists machine learning model development. Data generated will be used to train and test a machine learning model for predicting anisotropic mechanical behavior from the description of crystallographic texture. In the second application example, we will apply a similar workflow to correlate how the defect morphology affects the fatigue properties of metals. |
