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

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

Discrete and finite element co-simulation

Author: Claas Bierwisch
The possibility of coupling discrete element method (DEM) and finite element analysis (FEA) simulations is particularly attractive in order to model contact between granular matter and soft bodies. The coupling takes place at 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

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
