Progress on Manufacturing Simulation and Stress Driven Homogenization of Lithium Ion Battery electrode materials using the Finite Element Method - January 15, 2024

Note: This work will be the subject of an upcoming paper(s?) and is subject to change. Upon completion, this preface will be replaced with a link to the paper(s).Homogenized, finite element, multi-physics simulation of battery performance and aging via the Newman model is an efficient tool that aids in the design of lithium ion batteries at multiple scales. However, the accuracy of these homogenized models depends on the accuracy of the inputs, such as tortuosity and elastic moduli, which can va......

Thoughts on the nonlinear homogenization of dual phase, open cell meta materials, with a simple analytic example - October 21, 2023

The goal of micro-structure homogenization is to effectively capture the macroscopic properties of a material based on the materials and geometry that exist on the micro-scale. To do this, one can make the assumption that each macro-scale material point is represented by a micro-scale representative volume element (RVE). Then, the deformation gradient at the macro-scale would be applied as a constant to the entire boundary of the micro-scale RVE, implying that the deformation at the entire RVE b......
