Technological Problems and Experimental Investigation of Hybrid: Clinched - Adhesively Bonded Joint The choice of proper joining technology is an essential aspect of designing and manufacturing activity. New product designs enforce joining different materials in a new joining method. Clinching is a relatively new joining technology in which sheet metal parts are deformed locally without use of any additional element. Combining clinching with adhesive bonding seems to be interesting hybrid joining method with new potential applications in manufacturing industry. The paper deals with discussion of technological aspects and experimental investigations of clinched lap joints of different metal strips combined with their adhesive bonding, which can be applied for different branches of engineering. The main purpose of using different types of sheet metals was to analyze their influences on the geometry and mechanical strength of the clinched joint. The experiments with application of Digital Image Correlation (DIC) system ARAMIS allowed for exact monitoring of the deformation process of considered hybrid joint. The clinched joint test specimens were carried out with laboratory test-stand which consisted of a pair of tools (punch and die) attached to C-frame hydraulic press.
