Chemo-mechanics of lithium-ion battery electrodes
… mechanical deformation. Second, we studied the chemomechanically- coupled problem of lithiation of isotropic spheroidal phase-separating electrode particles. We showed that the coupling of mechanical deformation with diffusion is crucial in determining the lithiation morphology, and hence the Li …

Prediction of early-age cracking of UHPC materials and structures : a thremo-chemo-mechanics approach
… approach. The new model is a two-phase thermo-chemo-mechanical model, which is based on two pillars: the first is a hardened two-phase UHPC material model, and the second is a hydration kinetics model for ordinary concrete. The coupling of these two models is achieved by considering the …

Electro-chemo-mechanics of solids: application to all-solid-state batteries, polyelectrolyte gels, and actuators.
… movement of ions, and thus electrochemistry and mechanics are highly coupled in such systems. The overarching theme of this thesis is the theoretical formulation and numerical simulation of such systems. This thesis is divided into two major parts: Part 1. All-solid-state lithium metal batteries: …

A Computational Thermo-Chemo-Mechanics Framework for the Large-Scale Simulation of Material and Structural Failure in Hypersonic Environments
… Zone Modeling paradigm to thermo-chemo-fracture mechanics. The approach is distinguished by its unified DG treatment of the coupled problems, which facilitates the analysis of fracture propagation, fracture-dependent heat and mass transfer as well as thermally-activated solid-phase …

Continuum modeling of electro-chemo-mechanical phenomena in all-solid-state batteries
… commercialization of SSBs faces a series of chemo-mechanical issues across its constituents, namely growth induced fracture of solid-state electrolyte (SSE) due to metal deposition, interphase formation at the anode/SSE interface and damage of the various phases in composite electrodes. …

Bridging Atomistic, Mesoscale, and Systems Perspectives in the Design of Vanadium-Based Energy Storage Technologies
… A detailed understanding of electrochemistry—mechanics coupling and resulting emergent phenomena across many decades of length scales is imperative to unlock unexploited performance from existing battery chemistries, develop dynamic process controls, and design next-generation materials and …
