The fastener, characterized by an axisymmetric concave shape, is employed to fabricate hybrid busbar joints between electrically conductive strips of different materials and thicknesses. The self-clinching process with the new deformable fastener involves machining dovetail holes in both conductors and applying a squeezing force to the fastener to create a form-closed mechanical joint. The work encompasses both experimental investigations and numerical modeling using finite element analysis and is carried out on unit cells made from aluminum and copper conductors, which are representative of the joining process. The investigation evaluates force requirements, conducts destructive testing, and performs thermo-electric characterization of the new joints to conclude on the suitability of the new deformable self-clinching fastener for electric power distribution applications. Results indicate that while copper fasteners necessitate greater squeezing forces, they offer superior mechanical and thermo-electrical performance compared to aluminum fasteners in hybrid busbar joints.<\/jats:p>","DOI":"10.1177\/14644207241236463","type":"journal-article","created":{"date-parts":[[2024,3,1]],"date-time":"2024-03-01T03:02:16Z","timestamp":1709262136000},"page":"1898-1906","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A new deformable self-clinching fastener"],"prefix":"10.1177","volume":"238","author":[{"given":"Jo\u00e3o PM","family":"Pragana","sequence":"first","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Portugal"}]},{"given":"Rui FV","family":"Sampaio","sequence":"additional","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Portugal"}]},{"given":"Ricardo G","family":"Clara","sequence":"additional","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Portugal"}]},{"given":"Ivo MF","family":"Bragan\u00e7a","sequence":"additional","affiliation":[{"name":"CIMOSM, Instituto Superior de Engenharia de Lisboa, Instituto Polit\u00e9cnico de Lisboa, Portugal"}]},{"given":"Carlos MA","family":"Silva","sequence":"additional","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2630-4593","authenticated-orcid":false,"given":"Paulo AF","family":"Martins","sequence":"additional","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2024,3,1]]},"reference":[{"key":"bibr1-14644207241236463","unstructured":"Moseman A, Are electric vehicles definitely better for the climate than gas-powered cars?
