Recent developments in the modeling, analysis, and numerics of ferromagnetism

M Kruzik, A Prohl - SIAM review, 2006 - SIAM
Micromagnetics is a continuum variational theory describing magnetization patterns in
ferromagnetic media. Its multiscale nature due to different inherent spatiotemporal physical …

Rate-independent systems

A Mielke, T Roubíček - Applied Mathematical Sciences, 2015 - Springer
Our work on rate-independent systems was stimulated by our search for evolutionary
material models for shape-memory alloys that are flexible enough to encompass nonlinear …

[HTML][HTML] Stochastic phase-field modeling of brittle fracture: Computing multiple crack patterns and their probabilities

T Gerasimov, U Römer, J Vondřejc, HG Matthies… - Computer Methods in …, 2020 - Elsevier
In variational phase-field modeling of brittle fracture, the functional to be minimized is not
