The compliance of the connection, rivet tilt, peak contact pressures and slip amplitudes, in the absence of interference and clamp-up, are described. Rivet-panel slips in the double-row assembly are between 50–60% of those calculated for the single-row case. Contrary to the expectation that the second row of rivets might reduce the stress concentration factor by half, the additional row of rivets provides a reduction of only 28%.","PeriodicalId":231127,"journal":{"name":"Threaded and Riveted Connections, Design Issues, Reliability, Stress Analysis, and Failure Prevention","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131786721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, we carried out a modeling by finite elements of the threads stripping using an axisymmetric model and a criterion of rupture by damage. This modeling enabled us to study the various parameters which influence the behavior of a threaded assembly. To do so, we established an experimental design to know the most significant parameters. The result enables us to propose a simple rule for the optimization of the threaded assemblies whatever metallic materials of bolt and nut. We carried out tests of nuts threads stripping in order to validate this model. The estimated results are very close to those obtained by the tests.","PeriodicalId":231127,"journal":{"name":"Threaded and Riveted Connections, Design Issues, Reliability, Stress Analysis, and Failure Prevention","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129067529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
