Fatigue and Fracture Analysis
Crack Initiation & Fatigue Analysis
A close-up shows a fatigue crack running perpendicular to the weld bead, likely caused by:
- Cyclic loading
- Stress concentration at the weld toe
This highlights the need for:
- Non-destructive evaluation (NDE)
- Proactive maintenance
to ensure structural integrity in critical applications.
