Oct 10, 2025 - Visualizations from A Mesh-Free Multi-Physics Approach to Modeling Deep-Hole Drilling and Predicting Chip Jamming and Drill Failure
MPEG-4 Video - 1.2 MB - MD5: 78128c2ac9d9aa2bc4c3c1daca12e204
Acceleration of the chip by the metalworking fluid and impact of the FFR-based chip onto the artificial barrier. On the left side, the chip’s deformation is visualized. The visualization of drill, metalworking fluid, and chips is identical to Figure 5.3.
Simulation Results for Versatile Absorption Modeling for Transmissive Optical Elements Using Ray Tracing and Finite Element Analysis
Sep 26, 2025
Kurcsics, Mark; Eberhard, Peter, 2025, "Simulation Results for Versatile Absorption Modeling for Transmissive Optical Elements Using Ray Tracing and Finite Element Analysis", https://doi.org/10.18419/DARUS-5386, DaRUS, V1
Emerging quality requirements in modern optical systems increase the need for accurate simulation and compensation of disturbances. One key disturbance in high-power laser applications results from thermal loading due to absorption. The related paper presents a flexible modeling approach for absorption based on ray tracing, where point heat sources...

Experiment Video for Model Predictive Path-Following Control of a Quadrotor
Jun 26, 2025
Leprich, David; Rosenfelder, Mario; Hermle, Mario; Chen, Jingshan; Eberhard, Peter, 2025, "Experiment Video for Model Predictive Path-Following Control of a Quadrotor", https://doi.org/10.18419/DARUS-5099, DaRUS, V1
The provided video shows an experimental result of a Model Predictive Path-Following Controller (MPPFC) applied to a Crazyflie Quadrotor. The objective is to fly along the lemniscate path. The lemniscate is defined as a time-independent geometric curve, parameterized by a so-called timing law. Based on this, the MPPFC generates a dynamically feasib...

Experiment Video of Possibilistic Filtering and Optimization-Based Control of the Ball-on-Wheel System
May 12, 2025
Elangasinghe, Akila; Könecke, Tom; Schneider, Jan; Rosenfelder, Mario; Hanss, Michael; Eberhard, Peter, 2025, "Experiment Video of Possibilistic Filtering and Optimization-Based Control of the Ball-on-Wheel System", https://doi.org/10.18419/DARUS-5035, DaRUS, V1
The video provided shows two experimental results of a controlled Ball-on-Wheel system, each subjected to a different filtering and control method. The objective is to robustly stabilize the system's unstable equilibrium. In particular, the first part of the video demonstrates the real-time application of a Recursive Possibilistic Particle Filter (...

Simulation Results from an SPH Approach to Model the Influence of Assist Gas Forces in Laser Cutting
Apr 28, 2025
Kilittuwa Gamage, Ishan Anjana; Baumann, Andreas; Sollich, Daniel; Eberhard, Peter, 2025, "Simulation Results from an SPH Approach to Model the Influence of Assist Gas Forces in Laser Cutting", https://doi.org/10.18419/DARUS-5008, DaRUS, V1
Laser Cutting Laser cutting is a non-contact thermal-based material removal method that offers various advantages over conventional machining processes. The workpiece is melted by a high-powered laser beam and the resulting melt is blown away by a jet of gas. The laser assist gas is crucial as it influences the cutting speed, edge quality, and ther...
