Abstract Scope |
Deep material networks (DMN) are tree-like machine learning networks that train on linear homogenization relationships for a given microstructure, and then act as a representative volume element to predict non-linear material responses. Most DMNs are utilized for “single physics” problems, such as a DMN predicting the thermal or mechanical response using its predicted homogenized thermal conductivity or stiffness, respectively. However, a DMN architecture or training strategy involving multi-physics homogenization tasks is still not yet well established. Combining thermal and mechanical tasks will ultimately result in a better description of the deformation behavior of the composite for a wider variety of boundary conditions. In this study, a DMN is simultaneously trained to homogenize the stiffness and thermal conductivity of a composite. After training, the network extrapolates stress, strain, heat flux, and temperature gradient for non-linear thermomechanical relationships.
