Context
This dataset contains the scripts and processed data used for the numerical
investigations presented in Chapter 4 of the dissertation:

“Einsatz von CFK in hochpräzisen, lösbaren Welle-Nabe-Verbindungen im Maschinenbau am Beispiel von HSK-Werkzeugspannfuttern”.

The numerical study investigates the mechanical suitability of CFRP as a
substitute material for steel in high-precision HSK shaft–hub connections.
The focus is on the evaluation of stiffness behaviour, force ratios and
rotational limits based on a finite element model of the HSK interface.

Scope of the dataset
The dataset contains:

- Python scripts used to generate the Abaqus finite element models
- Python scripts used to execute the parameter studies
- Python scripts used for post-processing and evaluation
- Processed numerical results used for the figures and tables in Chapter 4

Large Abaqus output database files (.odb) are intentionally not included due
to their size and limited additional information content. The provided scripts
allow the full regeneration of the numerical models and the parameter studies.

Software and dependencies
The numerical models were generated and evaluated using:

- Abaqus (Finite Element Analysis software)
- Python scripting interface of Abaqus
- Python for post-processing

Exact software versions may influence numerical details but do not affect the
general methodology or conclusions.

Structure of the dataset
The dataset is structured as follows:

numerical_study/
    model_generation_scripts/
        Python scripts for creating the FE models in Abaqus

    parameter_study_scripts/
        Scripts for executing parameter variations

    evaluation_scripts/
        Scripts used for data extraction and evaluation

    results/
        Processed numerical results used in the dissertation

Reproducibility
All numerical results presented in Chapter 4 can be reproduced by executing
the provided model generation and parameter study scripts in Abaqus.

The dataset therefore focuses on the information required to regenerate the
models and reproduce the evaluation workflow.
