Fatigue strength evaluation of self-piercing riveted cold rolled steel joints under mixed mode loading conditions
Fatigue strength of cross-shaped specimens of SPR joints made of SPCC was evaluated at load angles of 0°, 45°, and 90°. For the static strength at load angles of 0°, 45°, and 90°, the maximum loads were determined to be 4890N, 1969N, and 1611N, respectively. Regarding for the relationship between the load amplitude and the number of cycles (Nf), the results were 014 . 0 3 . 2209 − = f amp N P ,...
متن کاملThe Influence of Ultrasonic Impact Treatment on Fatigue Behaviour of Welded Joints in High-strength Steel
The unabated growth of the steel industry and progressively increasing operating loads on metal structures generate a need for a search for optimum engineering solutions to improve the loadcarrying capacity and reduce metal consumption. One way of resolving this problem is to utilise high-strength steels. It is common knowledge however that the improvement of the steel strength is accompanied b...

متن کاملImproving Fatigue Strength of Welded Joints by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated with large-scale rolled beam and built-up specimens having yield strength of 345 to 760 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating t...
متن کاملUltra low cycle fatigue of welded steel joints under multiaxial loading
Ultra low cycle fatigue (ULCF) is a phenomenon that can be summarily defined as the deterioration of material properties under high amplitude cyclic loading, under which failure is reached typically within ten to twenty cycles. This phenomenon is observed in extreme loading scenarios such as earthquakes or exceptional winds where large cyclic strains are expected. Particularly sensitive are str...
