AE 590 Seminar Speaker: Mark Messner - Smarter Materials Modeling with AI, Physics, and Large Data

Abstract:
Machine learning and artificial intelligence have expanded our ability to quickly and reliably model and understand material performance. However, fully realizing their potential requires adapting the tools and methods used to develop materials models. These approaches also require—or can effectively leverage—far larger volumes of material testing and characterization data than traditional techniques, motivating changes in how test results are stored, managed, and accessed.

This presentation describes new modeling approaches for integrating large datasets, machine learning, and artificial intelligence into materials modeling platforms. Case studies include: (1) the use of uncertainty-aware, physics-based models combined with machine learning to improve extrapolation of long-term creep behavior relative to conventional empirical methods; (2) the practical use of large datasets, including long time series from detailed fatigue experiments, to train both conventional and machine-learning-based constitutive models; and (3) the combination of artificial intelligence, surrogate modeling, and optimization for inverse problems to guide the exploration and discovery of multifunctional composite materials.

These case studies also highlight freely available open-source tools developed at Argonne, including the NEML2 library for GPU-enabled constitutive modeling. The talk will conclude with perspectives, based on experience, on where AI is most helpful—and where it can be counterproductive—in the development of models for material behavior.
