- •
Cracks are predicted with standard solid finite elements with a high aspect ratio.
- •
Multiple arbitrary cracks can be simulated without the need of tracking algorithms.
- •
The strategy is developed integrally within the framework of the continuum mechanics.
- •
Mesh dependency can be prevented by the use of unstructured meshes.
- •
The technique is robust and stable and can be easily implemented in existing FEM code.
