| Abstract Scope |
Different Self-Pierce Rivets can be combined with different dies to cover a wide range of joint stacks. Often, there are a number of combinations that work for each joint stack meaning the optimal joint can be found by comparing cross-section parameters. Currently the parameters used are the interlock in the vertical and horizontal direction. This XY measurement does not accurately assess the amount of material above the flared rivet tip that needs to be defeated to pull out the rivet. In this study we showcase a new measurement approach where the area of the material above the rivet tip is measured to more accurately predict joint performance. An investigation of the relationship between the size of the ‘arealock’ and the strength of the joint in cross tension has indicated it is possible to predict both the strength and the energy absorbed at failure within 10% error |
