“…Figure shows the load amplitude, P amp (= (P max − P min ) / 2), against the number of cycles to failure, N f . Fatigue test results for U.A–L.A with the same Al‐5052 alloy sheet are included for comparison . The results show a relationship between the applied load amplitude and number of cycles,

“…SPR joints generally experience multiaxial stresses during fatigue loading. Recently, Kang and Kim tried to predict the fatigue lifetimes of SPR joints with different specimen configurations by adopting several fatigue parameters, such as the von Mises stress, maximum principal stress, and SWT (Smith–Watson–Topper) fatigue parameter . However, none of the parameters were sufficient to correlate the fatigue lifetimes of SPR joints for various types of specimen geometries.…”

“…However, the fatigue strengths with a cross‐tension configuration exhibited similar values. Recently, Kang and Kim attempted to predict the fatigue lifetimes of SPR joints with different specimen configurations by adopting an equivalent stress intensity factor (SIF). They argued that there is a good correlation between the experimental and calculated fatigue lifetimes with the equivalent SIF for SPR joint.…”

The self‐piercing riveting (SPR) process is gaining popularity because of its many advantages. This study investigated the fatigue strength of SPR joints in tensile‐shear specimens with dissimilar Al‐5052 and steel sheets. A structural analysis of the specimen was conducted. For this specimen, the upper steel sheet withstood applied load in a monotonic test and played a major role in the low‐cycle region. In the high‐cycle region, however, the harder surface of the upper steel sheet reduced the fatigue strength by enhancing fretting crack initiation on the opposite softer aluminium surface. Therefore, the fatigue endurance of the specimen was reduced. The fatigue endurance of a SPR joint with the combination of steel and aluminium sheets was found to be governed by the strength of the lower sheet, which is more vulnerable to the applied loading. Thus, it is desirable to use a stronger metal sheet as the lower sheet with regard to the fatigue performance. Scanning acoustic microscopy was effectively used to reveal and prove the formation and growth of subsurface cracks in SPR joints. The structural stress can predict the fatigue lifetimes of the SPR joint specimens within a factor of three.

“…It was found that these two events were able to be related to the path of the tip of the flaring rivet and hence the internal characteristics of the SPR samples via a simplified geometric approach. Static and fatigue tests were conducted using coach-peel, cross-tension and tensile-shear specimens with Al-5052 plates for evaluation of the fatigue strength of the SPR joints [10]. The results showed that the equivalent stress intensity factor range can properly predict the current experimental fatigue lifetime.…”
