Phase field simulation of fatigue crack propagation under complex load situations
Archive of applied mechanics (1991), 2020 Within this work, we utilize the framework of phase field modeling for fracture in order to handle a very crucial issue in terms of designing technical structures, namely the phenomenon of fatigue crack growth.

Accurate conservative phase-field method for simulation of two-phase flows [PDF]
Journal of Computational Physics, 2022 In this work, we propose a novel phase-field model for the simulation of two-phase flows that is accurate, conservative, bounded, and robust. The proposed model conserves the mass of each of the phases, and results in bounded transport of the volume ...

Vacuum Structure of the Ichimatsu-Decomposed Lattice Models [PDF]
, 2002 We proposed an `Ichimatsu'-decomposed lattice gauge theory with fermionic symmetries. The vacuum structures of the gauge sector with two coupling constants ($\beta_p,\beta_c$) are investigated for 3-dimensional Z$_2$ and 4-dimensional SU(2) cases using ...
