Title: Contribution to the recyclability assessment of multi-material structures with a focus on shredding

Author: M.Eng. Magdalena Heibeck

Faculty: Faculty of Mechanical Science and Engineering of the TUD Dresden University of Technology

Year: 2024

The repository contains zipped folders with selected data from the investigations discussed in thesis chapters (ch) 3, 4, and 5. It contains the following datasets, metadata, and scripts related to the research. More information is provided through README.txt files within the folders.

Experimental data for the shredding of profile and plate specimens (folders: ch3_profile_exp, ch5_plates_exp):

1. Feed characterization: photographs, mass, main dimensions of specimens
2. Shredding process evaluation:
   • Videos and screenshots of the shredding process, along with derived process descriptors (e.g., specimen orientation, number of rotor disks engaged)
   • Rotor moments of the shredder, including calculated specific mechanical energy consumption
3. Fragment characterization: photographs, 2D image analysis to determine fragment sizes, fragment properties (mass, material composition, liberation degree, size, final joint state, fracture phenomena, form-locks)

Simulation data for the shredding of profile and plate specimens (folders: ch4_profile_sim, ch5_plates_sim):

1. Ansys LS-DYNA input files: .k-files including geometry meshes (rotary shredder, specimen geometries, constraint boxes), boundary conditions (initial position and orientation of specimen, rotor angles), material models (steel, organosheet, rib structure), and tiebreak contact parameters for adhesion joints
2. Shredding process evaluation (refer to the experimental section)
3. Fragment characterization: .stl-files of fragments, fragment properties (refer to the experimental section)

Scripts:

• to characterize simulated fragments from .stl-files
• to read temporal simulation data from .binout-files
