Keynote Abstract
Decoding the electrode swelling for advanced battery diagnostics and life prognostics
The battery management system (BMS) relies on accurate prediction and management of complex electrochemical, thermal and mechanical phenomena. This raises the question of model and parameter accuracy that may allow the estimation of remaining useful life. To this end, novel sensing and diagnostic techniques based on “aging wrinkles” from battery cell swelling due to intercalation, particle fracture, rust-like film growth, and gas evolution will be presented. We will conclude by highlighting the ultimate BMS safety task, namely leveraging the battery swelling measurements for estimating the onset of venting and thermal runaway, and consequently, managing the risk of explosions and fires from failing batteries.

Keynote Abstract
Data-Driven Bayesian Model for Predicting Fatigue Crack Nucleation in Polycrystalline Ni-based Superalloys
This talk will discuss a Bayesian inference-based probabilistic crack nucleation model for the Ni-based superalloy Ren\’e 88DT under fatigue loading. A data-driven, machine learning approach is developed to identify the underlying mechanisms driving crack nucleation. An experimental set of fatigue-loaded microstructures is characterized near crack nucleation sites using scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) images for correlating the grain morphology and crystallography to the spatial location of crack nucleation sites. A concurrent multiscale model that embeds experimentally acquired polycrystalline microstructural RVEs in a homogenized material, is developed for fatigue simulations. The RVE domain is modeled by a crystal plasticity FEM, while a self-consistent homogenized anisotropic plasticity model is used for the exterior domain. The simulations create a database of state variables to be used in the model development. A Bayesian classification method is introduced to optimally select the most informative state variable predictors of crack nucleation and constructs a near-Pareto frontier of models with varying complexity. From this principal set of state variables, a simple scalar crack nucleation indicator is formulated, which encompasses relevant components derived from the main discriminators. This Bayesian inference approach allows the micromechanical state variables responsible for crack nucleation to evolve naturally from the existing data. The resulting model predicts the probability of nucleating a crack at a microstructural location, given the mechanical state of the material.
