Structures made of advanced materials (e.g., fiber composites and lattice materials) show strong material-structure coupling effects, meaning that the material microstructures significantly impact structural performance. Multiscale modeling could efficiently link features from different length scales to final structural analysis and design. However, technical barriers, such as a lack of design tools and infeasible computational costs, limit the potential of fully harnessing emerging lightweight materials to structural applications. SMML lab is developing several software tools and machine learning models to support innovative structural design using advanced tailorable composites. This work is supported by NASA and collaborates with Purdue and AnalySwift LLC.

In addition to DATC, we have developed several open-source tools for multiscale modeling of textile composites (texgen4sc) and general beam-like and plate-like composite structures (gmsh4sc).
