Sweeping granular matter with a flexible lamella

Author: Claas Bierwisch
The movie shows lamellas of different flexibility which are used to sweep cohesive granular matter by a lateral movement. The effectivity of the sweeping depends strongly on the rigidity of the lamella. Cleaning processes are appl ... more

Cleaning strength of abrasive particles added to toothpaste.

Author: Christian Nutto
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 ... more

Distortion of a complex shaped thin ceramic film during sintering on a rigid substrate simulated by Discrete Element Method

Author: Tobias Rasp
Particle-based simulations using the discrete element method were applied for the sintering of thin ceramic films that are constrained by a rigid substrate. The inhibition of lateral particle movement in vicinity of the substra ... more

SPH simulation of a particle impact on a ductile target

Author: Christian Nutto
The sequence shows an impacting body on a ductile target made of Al6061-T1. The impacting body is assumed to be ideally hard. The impact velocity is $45 \mathrm{m/s}$ and is tilted $51^°$ from the horizontal axis. The spacing of ... more
