| Abstract: |
| Based on the analysis and stochastic model for surface crack growth at weld toe, the limit state of the surface crack growth was discussed. A probabilistic method of assessing the fatigue life and safety of welded joints containing surface cracks is presented. |
| Key words: welded joint surface crack fatigue life safety probabilistic assessment |
