Self-piercing riveting (SPR) is a cold forming technique used to fasten together two or more
sheets of materials with a rivet without the need to predrill a hole. The application of SPR in …

Achieving high-strength joints with flat surfaces is of significant importance for reducing wind
resistance and enhancing aesthetic appeal. In this study, a novel flat-die friction self-piercing …

In recent years, the transportation industry has faced the challenge of cutting costs, meeting
increasingly stringent environmental regulations, and significantly increasing transportation …

Friction stir welding (FSW) has been applied to many fields including aerospace
manufacturing and the railway industry. However, the interfacial friction behavior remains …

The lap joints of 6061-T6 aluminum alloy/Q235 steel were obtained by conventional friction
stir welding (FSW) and ultrasonic vibration enhanced friction stir welding (UVeFSW). The …

This experimental investigation describes the effect of tilt angle and rotational speed on the
characteristics of welding defects, intermetallic compounds, weld strength and micro …

By combining experimental SPR tests with a finite element (FE) model, the influences of top
sheet thickness (T t), bottom sheet thickness (T b) and rivet length (L) on the joint formation …

The joint strength of self-piercing riveting is a key factor for evaluating riveting quality. Shot
peening is a useful process to strengthen sheet metal. To improve the performance of self …

We analyze the role of different rivet and die design parameters on the feasibility and quality
of the self-piercing riveting (SPR) joining of metallic sheet stacks. In particular, the riveting of …

One thin 5000 series aluminium alloy sheet and two thin 980 MPa grade cold rolled ultra-
high strength steel sheets were joined by self-pierce riveting and mechanical clinching …
