“…As the world pays more and more attention to the energy saving, environmental protection and economy of automobiles, lightweight metallic and non-metallic materials are used abundantly in the field of automobile production [1–3]. The use of lightweight metal materials, especially aluminium alloys, instead of steel and iron to reduce the weight of the body is indeed an effective measure [4–8]. The continuous application of the lightweight engineering structures has led to the development of plastic joining technology.…”

The increasing availability of high-performance materials has boosted the demand for advanced joining techniques for heterogeneous sheets in the industry. The novel stepped clinching process (SCP) may become a new option for joining sheets due to the superiority in joint strength and geometric parameters compared to conventional clinching technology. The SCP for joining AA5052-H32 and Polyoxymethylene is explored experimentally in the paper. The failure mechanism of stepped clinched joints is studied at both macroscopic and microscopic levels. Increasing the forming force assists in increasing mechanical strength and improving cross-sectional geometry. The optimal energy absorption values and shear strength of 5.038 J and 2040 N were obtained in the experiments when the forming force was 32 kN.
