| Abstract: | FEA model of a B-type metro aluminum alloy carbody including weld line was established.Based on the mesh-insensitive structural stress method and main S-N curve method in ASME standard,stress concentration,fatigue life and damage were calculated for each key weld line.The results showed that the fatigue life of all weld line had reached the carbody design life. |
