Microscopic fracture topology evolution


© Institute of Applied Mechanics

The simulation shows a phasefield based modelling of fracture processes within materials with distinct microstructure. Spherical stiff inclusions (pink) are embedded into a soft matrix. The crack surface (red) evolves around the spherical stiff inclusions and perpendicular to the horizontal macroscopic stretch direction. The simulation is carried out using a fast-Fourier-transform based solution scheme. Goal of the current research is inter alia the characterization and design of 3D-printed smart materials in lightweight applications. Felix Selim Göküzüm M.Sc.
