“…This investigation will be developed further to create the numerical model of the joint, which will take into account gradual degradation of the adhesive layer and cracking process in the plastic adherends, in order to extend previously formulated damage and cracking models for materials (e.g. [32][33][34][35][36][37][38][39] and other types of the hybrid joints [19][20][21][22][23][24][25] and [28][29][30]). …”

Digital Image Correlation (DIC) technique gives possibility to observe deformation process in many applications including self-piercing riveting (SPR) hybrid joint. The hybrid SPR joint consists of simple SPR joint made of two adherends, steel tubular rivet (total length of 5 mm) and an adhesive. The adhesive was applied before piercing process.For specimen preparation two different aluminum alloys were used: 2024 and 5005 (2mm thickness both) with tensile strength 400 and 160MPa, respectively. For better understanding of joint forming process and to allow DIC strains observation during the joint creation, a special holder was designed with precisely polished die. The tests were performed by application of the 100kN servo-hydraulic machine, which recorded time, load, displacement and was synchronized with the DIC system.The joint forming process was carried out with 2 mm/min constant speed. During piercing process rivet and upper surface of the adherend were observed and the major strain states were estimated. The uniaxial tensile tests of single lap joints (SLJ) up to the final failure were performed and the displacements and the strains were recorded. In particular the rivet deformation was observed also during the whole loading process.The hybrid SPR joints are very effective, because the load capacity and energy absorption increase more than 1.5 times in comparison to the simple SPR joints.Keywords: DIC, SPR, joining process, hybrid joint Technika Cyfrowej Korelacji obrazu (DIC) pozwala na obserwacje procesów deformacji w różnych aplikacjach -w tym dla hybrydowych połączeń typu SPR (przebijanych za pomocą nita). Hybrydowe połączenie typu SPR składa się ze standardowego połączenia SPR -próbka jednozakładowa przebita stalowym nitem pół-rurkowym (długość całkowita 5 mm) oraz warstwy kleju pomiędzy zakładkami naniesionego przed procesem przebijania. Do stworzenia próbek zostały użyte dwa typu aluminium o różnej plastyczności 2024 i 5005 o grubości 2 mm każdy i wytrzymałości odpowiednio 400MPa i 160 MPa. W celu pełniejszego zrozumienia procesu formowania się złącza został zaprojektowany specjalny uchwyt z precyzyjnie wyszlifowaną matrycą. Badania zostały przeprowadzone przy pomocy maszyny osiowej o zakresie 100kN, zsynchronizowaną z systemem DIC.Proces tworzenia się złącza był prowadzony ze stałą prędkością 2 mm/min. Podczas procesu tworzenia złącza obserwowano nit oraz górną powierzchnię łączonych blach i główne odkształcenia zostały wyznaczone. Badania przeprowadzono na próbkach zakładkowych do ich zniszczenia rejestrując przemieszczenia i odkształcenia. W szczególności obserwowano deformację nita w całym procesie deformacji.Hybrydowe połączenia typu SPR są bardzo efektywne, ponieważ uzyskuje się wzrost siły przenoszonej przez połączenie i energii absorbowanej ponad 1.5 raza większych w porównaniu do prostego złącza typu SPR.

“…Moroni et al have studied the influence of the factors such as plate spot, thickness, joint distance, aging treatment and temperature on resistance spot welding, punch riveting, traditional riveting, SPR connection [15] . The results show that the overall performance of the composite joint is much higher than that of the mechanical joint alone.…”

Abstract-Lightweight is an inevitable trend for the future development of automobile bodies. There are several suitable for steel-aluminum lap connection technology, with the application of steel-aluminum hybrid body. Mechanical connection technology, welding technology and adhesive riveting composite connection technology are introduced in the paper. The idea of a hybrid material body structure based on the concept of "suitable materials for the right part" is a good balance between the requirements for lightweighting, processability, safety and cost as a whole. It represents the future development of automotive body structure of the latest trends.
