- •
SBFEM is extended to analyse various types of crack in 3D problems.
- •
No singular element, excessive refinement or path-independent integral is required.
- •
No a priori knowledge on the stress asymptotic solutions is needed.
- •
The order of stress singularity is obtained directly from an eigenvalue solution.
- •
Extraction of stress intensity factors and T-stress based on their definitions.
