Abstract Fatigue behaviors of hybrid joint, the combination of cold-formed mechanical fastening with adhesive bonding, are yet to be understood comprehensively even though they have been widely used in industries. The lack of understanding is mainly attributed to the complicated load transfer path and possible interactions between the two types of joining techniques, namely mechanical interlocking and adhesive bonding. In the present work, fatigue tests are performed on self-piercing riveted (SP...

Abstract Fatigue life prediction of advanced high strength steels (AHSS) spot welded joints is of great importance for autobody design with AHSS being increasingly used. In the present work, the fatigue failure behaviors of the DP780GI spot welded joints under the tensile shear (TS) and coach peel (CP) loading conditions are experimentally investigated and numerically modelled. Two failure modes, eyebrow failure and weld button pull out occur in the tests of TS joints, while only interfacial fra...

Abstract The yield strength of the UOE pipe is different from raw steel plate and inhomogeneously distributed on pipe body, because of the Bauschinger effect and work hardening during UOE forming process. The yield strength development of high-strength pipeline steels from raw plate to UOE pipe is investigated by using a modified Chaboche hardening model that incorporates the Bauschinger effect and yield plateau of X70, X80 and X90 steels. The final yield strength of pipe is evaluated by finite ...

Abstract Large diameter welded pipes used in oil and gas pipelines are primarily manufactured by the UOE process, which consists of U-forming, O-forming, and expansion procedures. The formation of O-forming gap in the O-forming stage is a key processing factor and it involves complex plastic deformation and springback of the steel plate. In this paper, a numerical method is proposed for predicting geometric configuration and O-forming gap of steel plate after C–U–O-forming. A combined hardening ...

Abstract Magnesium alloy GW103 samples were heat treated to different ageing conditions and then shot peened using process parameters that deliver optimized high cycle fatigue (HCF) life. Significant HCF life improvements were observed in all samples, with a peak-aged sample showing the biggest increase. In order to simulate the effect and evolution of residual stresses during low cycle fatigue (LCF), a Finite Element (FE) model was employed, taking into account both the shot-peening-induced pla...
