Abstract Scope |
We made an effort to accelerate the crystal plasticity (CP) model predictions of macro and grain level deformation behavior of a dual phase (DP) steel using Machine Learning (ML) models. We use experimentally validated CP model predictions to generate ML training datasets. To inform microstructure-property relation to ML dataset for DP steels, synthetic RVEs were generated using Dream3d with controlled microstructural variations. These RVEs were used to perform CP simulations using DAMASK under multiple loading conditions. Postprocessing was performed to prepare the training dataset used for training of ML models. The trained ML models showed excellent predictive capability for both macroscopic as well as grain-level deformation for a completely randomized RVE. This ML accelerated CP modeling approach enables accurate, data driven stress prediction and yield behaviour analysis, offering a robust framework for the accelerated design to high performance metallic alloys. |
