Topic: Exploring the low-data regime in hyperelasticity and elastoplasticity
Abstract: Machine learning techniques are gearing up to play a significant role in the field of computational solid mechanics and multiphysics, enabling the integration of experimental data and physical constraints towards data-driven constitutive laws, acceleration of computational techniques for multi-scale modeling, and new paradigms for the solution of forward and inverse problems, to name a few. This talk will cover recent advancements in the area of ML-enabled constitutive modeling I) A physics-informed data-driven constitutive modeling approach for isotropic and anisotropic hyperelastic materials is developed using tensor representation theorems. The trained surrogates (using laGPR and NNs) are able to respect physical principles such as material frame indifference, material symmetry, and the local balance of angular momentum. Overall, the presented approach is tested on synthetic data from isotropic and anisotropic constitutive laws and shows surprising accuracy even far beyond the limits of the training domain, indicating that the resulting surrogates can efficiently generalize as they incorporate knowledge about the underlying physics. Additionally, it is shown that the inherent material symmetries can be discovered directly from data. II) Finally, we proceed to tackle elastoplasticity in a modular framework. Employing convexity for the yield functions we recover texture-parametrized yield functions using input convex (IC)NNs and propose a hybrid model-data-driven framework to recover yield functions with tension compression asymmetries in the low data regime. Additionally, by employing thermodynamic requirements in an NN-based framework we learn hardening laws from limited experimental data.

Jimmy Quon Lecture: Valorizing Gas Streams Containing CO2 and CO- Bruce Rittman
McCormick - Civil and Environmental Engineering (CEE)
2:00 PM A230, Technological Institute
EVENT DETAILS
Abstract: Carbon dioxide (CO2) is the most important greenhouse gas, and carbon monoxide (CO) is acutely toxic. Release of these gases must be halted. One promising approach is microbiological valorization of CO2 and CO in off-gas streams. Valorization means converting the CO2 or CO to valuable organic compounds that are feedstock for the chemical and energy industries. This talk describes two distinctly different examples of valorization. The first example is valorizing the CO2 in digester biogas using photosynthetic microalgae. The benefits are to generate more methane (CH4) while converting the biogas (~65% CH4) to higher-value biomethane (>97% CH4). The second example is conversion of syngas (a mixture of CO, CO2, and hydrogen (H2)) to organic acids and alcohols using CO-fermenting and chain-elongating bacteria.
Bio: Dr. Bruce E. Rittmann is Regents Professor of Environmental Engineering and Director of the Biodesign Swette Center for Environmental Biotechnology at Arizona State University.

Dr. Rittmann is a member of the National Academy of Engineering; a Fellow of AAAS, WEF, IWA, AEESP, and NAI; and a Distinguished Member of ASCE. Dr. Rittmann was awarded the first Clarke Prize for Outstanding Achievements in Water Science and Technology from the NWRI, the Walter Huber Research Prize and the Simon Freese Award from ASCE, the G.M. Fair Award from AAEES, the Perry L. McCarty/AEESP Founders Award, and the Camp Applied Research Award from WEF. He is the co-winner of the 2018 Stockholm Water Prize. Dr. Rittmann has published over 880 journal articles, books, and book chapters, and he has 25 patents. With Dr. Perry McCarty, Dr. Rittmann co-authored the textbook Environmental Biotechnology: Principles and Applications (McGraw-Hill Book Co.), which is now out in its second edition.
