Abstract Scope |
Recently, machine learning has enabled the development of computational simulations for rapid material analysis and design with surrogate agile and accurate models. Deep Material Network (DMN) is known to be a powerful approach with its ability to extrapolate the constitutive equations and its lower computational cost. In this study, DMN has been expanded to thermal conductivity analysis, which was previously limited to elastic mechanical problems. We had performed thermal conductivity homogenization of woven composites, considering two-scale homogenization. To consider the orthotropic material properties, micromechanics-based DMN network parameters have been updated to reflect the material's orientation and rotation. We show how DMN could be used as a surrogate model to deal with large variances in uncertain material properties. We believe our DMN model will open new chances for multiphysics, multiscale design and analysis of composite materials.
