| Abstract: |
Extension of the fatigue life of welded joints made of circular hollow sections.To investigate the applicability of high frequency hammer peening methods on hollow section joints, experimental investigations as well as numerical investigations are required. Within the research programme CIDECT 7Y-PWT, numerical investigations are carried out at the Karlsruhe Institute of Technology (KIT). Fatigue tests are performed on CHS-X-joints with and without high frequency hammer peening (HFHP) Test results show a significant fatigue life extension for CHS-X-joints. Compared to the CIDECT Design Guide 8, fatigue strength is increased by 70 to 90 %. |
