Sharp phase-field modeling of isotropic solidification with a super efficient spatial resolution
Michael Fleck, Felix Schleifer
The numerical resolution efficiency of phase-field models is limited by grid friction, grid anisotropy and pinning. The 1D sharp phase-field model eliminates grid friction and pinn…
Phase-field modeling of microstructure formation in Ni-based superalloys with high volume fraction
Felix Schleifer, Markus Holzinger, Yueh-Yu Lin +2
The excellent mechanical properties of the Ni-based superalloy IN718 mainly result from coherent precipitates. Due to a strongly anisotropic lattice misfit between the matrix…
Frictionless motion of diffuse interfaces by sharp phase-field modeling
Michael Fleck, Felix Schleifer, Patrick Zimbrod
Diffuse interface descriptions offer many advantages for the modeling of microstructure evolution. However, the numerical representation of moving diffuse interfaces on discrete nu…
Phase-field modeling of Li-insertion kinetics in single LiFePO\textsubscript{4}-nano-particles for rechargeable Li-ion battery application
Michael Fleck, Holger Federmann, Evgeny Pogorelov
We develop a continuum phase-field model for the simulation of diffusion limited solid-solid phase transformations during lithium insertion in LiFePO4-nano-particles. The solid-sol…
Spinodal Gap Dependence on Size and Boundary Reaction Rate for Intercalation in Nanoparticles
E. Pogorelov, M. Fleck, H. Federmann +2
Using mathematical model for intercalation dynamics in phase-separating materials proposed in (Singh, G. K.; Ceder, G.; Bazant, M. Z. Electrochimica Acta 2008, 53, 7599) and develo…
Fracture as a pattern formation process
M. Fleck, D. Pilipenko, R. Spatschek +1
A continuum model of crack propagation is presented and discussed. We obtain steady state solutions with a self-consistently selected propagation velocity and shape of the crack, p…
