A series of laser joining experiments between polyethylene terephthalate (PET) and aluminium alloy (A5052) were conducted to investigate the effect of anodizing on A5052 surface on dissimilar materials used in joining. In this study, PET/A5052 joints with anodized A5052 surface exhibited greater shear strength compared to PET/A5052 joints without anodizing. The shear strength of the joints was ...

This qualitative study examines membership processes in groups operating in an uncertain environment that prevents them from fully predefining new members' roles. I describe how nine elite high-end, cutting-edge culinary groups in the U.S. and Europe, ranging from innovative restaurants to culinary R&D groups, use negotiated joining-a previously undocumented process-to systematically construct ...

Abstract Due to the increasing use of multi-material constructions and resulting material incompatibilities, mechanical joining technologies are gaining in importance. The reasons for this variety possibilities as well high load-bearing capacities. However, currently rigid tooling systems cannot react changing boundary conditions, such changed sheet thicknesses or strength. For reason, a large ...

Clinching technology has better performance in joining different sheet materials. However, the protuberance and mechanical behaviors of clinched joints have always been needed to be improved. In this paper, a new clinching method, named two-strokes flattening (TFC) process, was proposed improve flatten protuberance. Mechanical testing including tension-shearing tests employed under quasi-static...

Flow-drill screwing is one of the key joining technologies for car body structures in multi-material lightweight design. In course technological developments and subsequent volume production a product, different assets are used to obtain same joints, assuming that similar processes yield joint characteristics. Since simple transfer process parameters materials usually not possible, remarkable e...
