To overcome the limitations of existing finite element tools, a modular Python framework has been developed to automate three-dimensional crack growth simulations. The program combines geometric reconstruction, adaptive remeshing, and the numerical evaluation of fracture mechanics parameters within a single, fully automated workflow. The framework builds on open-source components and remains solver-independent, enabling straightforward integration with commercial or research finite element codes. A dedicated sequence of modules performs all required steps, from mesh separation and crack insertion to local submodeling, stress and displacement mapping, and iterative crack-front update, without manual interaction. The methodology was verified using a mini-compact tension (Mini-CT) specimen as a benchmark case. The numerical results demonstrate the accurate reproduction of stress intensity factors and energy release rates while achieving high computational efficiency through localized refinement. The developed approach provides a robust basis for crack growth simulations of geometrically complex or residual stress-affected structures. Its high degree of automation and flexibility makes it particularly suited for analyzing cracks in clinched and riveted joints, supporting the predictive design and durability assessment of joined lightweight structures.}}, author = {{Krome, Sven and Duffe, Tobias and Kullmer, Gunter and Schramm, Britta and Ostwald, Richard}}, issn = {{2076-3417}}, journal = {{Applied Sciences}}, number = {{1}}, publisher = {{MDPI AG}}, title = {{{Validation and Verification of Novel Three-Dimensional Crack Growth Simulation Software GmshCrack3D}}}, doi = {{10.3390/app16010384}}, volume = {{16}}, year = {{2025}}, } @misc{63764, author = {{Weiß, Deborah and Krome, Sven and Duffe, Tobias and Kullmer, Gunter and Ostwald, Richard}}, publisher = {{LibreCat University}}, title = {{{Experimentelle Ermittlung von Rissablenkungswinkeln bei außerphasiger Mixed-Mode-Belastung mittels einer neuartigen Probengeometrie}}}, doi = {{https://doi.org/10.48447/BR-2025-490}}, year = {{2025}}, } @article{65004, author = {{Knaup, Felix and Brüning, Florian}}, journal = {{Extrusion}}, keywords = {{Aufschmelzen, extrusion, Messtechnik}}, pages = {{28–33}}, title = {{{Vergleich experimenteller Methoden zur Untersuchung des Aufschmelzprozesses in Einschneckenextrudern}}}, year = {{2025}}, } @inproceedings{65227, author = {{Tölle, Laura and Rehmer, Torben and Müller, Johann and Ruppel, Fynn and Trier, Matthias}}, location = {{Chemnitz, Germany}}, title = {{{Disentangling Negative Sentiment towards Virtual Influencers: Towards a Taxonomy of Criticism}}}, year = {{2025}}, } @inproceedings{65229, author = {{Tölle, Laura and Nolting, Max and Trier, Matthias}}, location = {{Dresden}}, title = {{{Using ChatGPT for Identifying Negative Structures in Social Media Conversations}}}, year = {{2025}}, } @inproceedings{61103, abstract = {{Verification planning for engineering complex systems lacks a systematic procedure for creating test scenarios.
