Research on the mechanical properties of repaired clinched joints with different forces
Abstract Recently, lightweight materials have been increasingly used to build engineering structures, especially automotive structures. Mechanical clinching, an advanced joining technology, is widely used to join lightweight materials on the structures. The clinched joint may be deformed or damaged when it bears higher shearing forces. Till now, there is no effective repairing technology to repair deformed/damaged clinching joints. A novel repairing process is thus proposed and studied in this paper. A custom-built rivet and two flat dies were used as main repairing tools. Different damaging forces were applied on clinched joints to produce different damaged joints. The damaging force, cross-sectional profile, neck thickness, and shearing force of the repaired joints were investigated. The novel process is suitable to repair deformed/damaged clinching joints. As for the deformed joint, the deformed neck can be reshaped to restore to its original shape in the repairing process. As for the damaged joint, the separated sheets are hooked by a new interlock generated by the custom-built rivet. Compared with clinched joint, the repaired joint can get higher shear strength, which is significant for the safety of engineering structures.
Highlights A novel repairing process for clinched joint on thin-walled structures was proposed. The interlock can be repaired by a custom-built rivet and two flat dies. The repaired joint can get higher strength than clinched joint. The repaired joint can get higher energy absorption than clinched joint.
