This process consists of applying an inner pressure combined with an axial displacement to manufacture the part. During the manufacturing phase, inappropriate choice of the load paths can lead to failure. Deterministic approaches are unable to optimize the process by taking into account the uncertainty. So we introduce the reliability-based design optimization (RBDO) to optimize the process under probabilistic constraints to ensure a high reliability level and stability during the manufacturing phase and avoid the occurrence of such plastic instability. Taking some uncertainties into account the process is very stable and associated with a low failure probability. The definition of the objective function and the probabilistic constraints take advantage of the forming limit diagram (FLD) and the forming limit stress diagram (FLSD) used as a failure criterion to detect the occurrence of wrinkling, severe thinning and necking. To validate the proposed approach, the THP is then introduced as an example. The numerical results show the robustness and efficiency of the RBDO to improve thickness distribution and minimize the risk of potential failure modes.<\/jats:p>","DOI":"10.1177\/0037549712441986","type":"journal-article","created":{"date-parts":[[2012,6,7]],"date-time":"2012-06-07T23:35:03Z","timestamp":1339112103000},"page":"1129-1137","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Reliability-based design optimization analysis of tube hydroforming process"],"prefix":"10.1177","volume":"88","author":[{"given":"A","family":"El Hami","sequence":"first","affiliation":[{"name":"LMR, National Institute of Applied Sciences, St Etienne du Rouvray, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Radi","sequence":"additional","affiliation":[{"name":"LMS, FST Settat, Route de Casablanca, Settat, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Cherouat","sequence":"additional","affiliation":[{"name":"GAMMA3, UTT, Troyes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,6,7]]},"reference":[{"key":"bibr1-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2004.05.018"},{"key":"bibr2-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2007.02.050"},{"key":"bibr3-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-0136(03)00778-7"},{"key":"bibr4-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmachtools.2005.01.029"},{"key":"bibr5-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmecsci.2005.02.003"},{"key":"bibr6-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7403(02)00177-7"},{"key":"bibr7-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2005.05.027"},{"key":"bibr8-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-0136(01)01219-5"},{"key":"bibr9-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.ress.2008.02.024"},{"key":"bibr10-0037549712441986","first-page":"13","volume":"17","author":"Chu GN","year":"2010","journal-title":"Indian J Eng Mater Sci"},{"key":"bibr11-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1007\/s00170-009-2237-y"},{"key":"bibr12-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1007\/s00170-009-2072-1"},{"key":"bibr13-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2006.12.002"},{"key":"bibr14-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1080\/10426910601134195"},{"key":"bibr15-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1007\/s00170-007-1015-y"},{"key":"bibr16-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2007.02.050"},{"key":"bibr17-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-0136(03)00854-9"},{"key":"bibr18-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.compstruc.2003.09.002"},{"key":"bibr19-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/0167-4730(94)90039-6"},{"key":"bibr20-0037549712441986","doi-asserted-by":"publisher","DOI":"10.2514\/1.9036"},{"key":"bibr21-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1115\/1.2218344"},{"key":"bibr22-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1002\/nme.954"},{"key":"bibr23-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1115\/1.2716427"},{"key":"bibr24-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/S0045-7825(02)00394-8"},{"key":"bibr25-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/S0890-6955(01)00048-7"},{"key":"bibr26-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.commatsci.2007.07.014"},{"key":"bibr27-0037549712441986","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmatprotec.2007.09.005"},{"key":"bibr28-0037549712441986","volume-title":"Response Surface Methodology: Process and Product Optimization using Designed Experiments","author":"Myers RH","year":"2009"},{"key":"bibr29-0037549712441986","unstructured":"ABAQUS Inc. 2005.
