Bulging and buckling of a hose under pressure

Author: Claas Bierwisch
The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves downward through the pipe thereby pushing the fluid into the hose which is sealed by a disc at the lower end. The hose bu ... more

Spray drying of single drops/granules

Author: Thomas Breinlinger
Spray drying is a process used to transform fine primary powder into larger granules which provide better characteristics (e.g. flowability, pressability etc.). Our simulations focus on the evolution of the microstructure of the i ... 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

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

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

Fluid flow from a hose under gravity

Author: Claas Bierwisch
The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves towards the left through the pipe thereby pushing the fluid out of the hose. Gravity is accelerating the fluid downwards. ... more

Simulation of a tensile test using smoothed particle hydrodynamics (SPH)

Author: Christian Nutto
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 o ... more

Tire traction

Author: Claas Bierwisch
Discrete Element Method (DEM) simulations can be used to model the traction of a tire on a granular ground. The DEM force laws can be parameterized in order to represent various types of grounds ranging from sand over mud to snow. ... more

Cleaning strength of abrasive particles added to toothpaste (half cut).

Author: Christian Nutto
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 w ... more
