text: The accurate prediction of crack initiation and propagation is essential
for assessing the structural integrity of mechanically joined components and other
complex assemblies. 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.
