Inclined Tube‐Sheet Plastically Deformed Joints

Abstract

The purpose of this paper is to provide readers with a broad understanding of inclined tube‐sheet joints produced by plastic deformation that will enable them to identify the major operating parameters, to determine the process window and to design tooling systems for producing strong, flexible, and environmentally friendly assemblies. The methodology draws upon the fundamentals of asymmetric local buckling of thin‐walled tubes subjected to axial compression and introduces two different process setups for assembling sheets to tubes at different inclination angles that can easily and effectively join dissimilar materials, at room temperature. The presentation is illustrated by selected test cases obtained from a comprehensive numerical and experimental research work. The overall content of the paper widens and enhances previous work published by the authors and is a step forward in joining sheets to tubes by plastic deformation. Potential applications of the proposed technology foster creative and innovative ideas in design for assembly for the benefit of those who work with sheets and tubes in daily practice.

Innovative cold joining technologies based on tube forming

“…The new proposed technologies for connecting tubes [3] and fixing tubes to sheets [4] are schematically shown in Figure 2. The idea behind the technologies is based on controlling the development and propagation of plastic instability waves in thin-walled tubes subjected to axial compression beyond the bifurcation point of the load-displacement curve.…”

High-speed joining of tubes to panel sheets using electro-hydraulic forming

“…Finally, in the case of the brazed joints, there are some di culties in tting the tube and the sheet together with very tight tolerances [4]. These limitations have led to the invention of some modern techniques such as joining by forming.…”

Joining end-to-end tubing of dissimilar materials by forming

“…In the past months, Gonçalves et al [3,4] developed innovative plastic deformation solutions for joining tubes to sheets and for producing tube attachments of dissimilar materials at an angle to the axis of the main tube. The solutions are based on a combination of plastic instability and locking by means of compression beading, and a patent application by a manufacturer of automotive components protects the utilization of these solutions for connecting the lever and the fulcrum of a car hand-brake system [5].…”
