Abstract Scope |
In recent years, the Deep Material Network (DMN) has emerged as a powerful method for developing reduced order models in composite modeling. Unlike other machine-learning approaches for reduced order models, the DMN focuses on learning microstructure interactions rather than material behavior under specific loading paths. This unique feature allows for extrapolating to other constitutive behaviors without the need for retraining. Traditionally, DMNs have been trained using linear homogenized material properties, making use of low-cost direct numerical simulation data. However, a critical question arises: Why restrict ourselves to homogenized material properties when we have access to a wealth of information gathered during direct numerical simulations? In this study, we have expanded the capabilities of the DMN by training it with homogenized and local field information. We have updated the DMN architecture to incorporate linear local information during training, and our results demonstrate how this novel approach enhances the performance of DMNs. |
