#### 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
