A cut finite-element method for fracture and contact problems in large-deformation solid mechanics
Computer Methods in Applied Mechanics and Engineering, 2022 Cut finite-element methods (CutFEMs) belong to the class of methods that allow boundaries/interfaces to cut through the elements, which avoids any meshing/remeshing problems.

Contact mechanics for polydimethylsiloxane: from liquid to solid
Soft Matter, 2018 Adhesion between a glass ball and a polydimethylsiloxane (PDMS) sample is dependent on the PDMS cross-link density, and the transformation of the material from the uncrosslinked liquid state to the fully crosslinked solid state is investigated in this study.

A novel face-on-face contact method for nonlinear solid mechanics
Computer Methods in Applied Mechanics and Engineering, 2019 The efficient solution of quasistatic contact problems in nonlinear solid mechanics continues to pose some challenges. Traditional node-to-segment methods are not guaranteed to pass the contact patch test, and exhibit non-smooth contact behavior in the ...

Contact Mechanics of Solid-State Batteries
Journal of Electrochemical Energy Conversion and StorageThe performance and stability of all-solid-state batteries (ASSBs) are critically dependent on the mechanical contact at their solid-solid interfaces. Poor contact between electrodes and the solid electrolyte results in a limited real area available for charge transfer, leading to increased interfacial impedance and performance degradation during ...

The Schwarz alternating method for multi-scale coupling and contact in solid mechanics.
Proposed for presentation at the 3rd Pan American Congress on Computational Mechanics (PANACM) 2021 held November 9-12, 2021 in Online, Brazil, 2021 Multi-scale methods are essential for the understanding and prediction of behavior of engineering systems when a small-scale event will eventually determine the performance of the entire system.

A treatment of particle–electrolyte sharp interface fracture in solid-state batteries with multi-field discontinuities [PDF]
Journal of the mechanics and physics of solids, 2023 In this work, we present a computational framework for coupled electro-chemo-(nonlinear) mechanics at the particle scale for solid-state batteries. The framework accounts for interfacial fracture between the active particles and solid electrolyte due to ...
