The video shows a thoothbrush filament moving through a numerical model of a toothpaste enriched with abrasive particles. At the bottom of the simulation domain, an idealistic model of enamel is implemented. It was studied how the abrasive particles interact with the toothpaste fluid and the toothbrush filament. The influence of the abrasive character of the toothpaste can be studied by the induced stresses into the surface of the enamal.

The video of the simulation shows a thoothbrush filament moving through a numerical model of a toothpaste enriched with abrasive particles. At the bottom of the simulation domain, an idealistic model of enamel is implemented. It was studied how the abrasive particles interact with the toothpaste fluid and the toothbrush filament. The influence of the abrasive character of the toothpaste can be studied by the induced stresses (colored in red) into the surface of the generic enamal. For a clearer identification of the induced stresses, the fluid is shown in a half-section.

The video shows the simulation of a tensile test. The tensile specimen is shown in a half-section. The color scheme represents the plastic strain occurring during the strain. The end of the videos shows a stress-strain diagramm of the simulation in comparison with the experiment.
