Research ArticleOpen accessIn the keywordsFracture and springback on Double Bulge Tube Hydro-FormingF. Djavanroodi, M. GheisaryThis research aims to establish a basic understanding of Double Bulge Tube Hydro-Form processing of stainless steel deep drawn cups. The method is briefly reviewed by carrying out experimental tests and Finite element analysis. By measuring bulge height in both formed curves by Coordinate measuring machine (CMM) and thickness variation specimen by Ulterasonic thickness measurment device (UTM), it has been … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalytical and Numerical Analysis of Free Bulge Tube HydroformingF. Djavanroodi, M. Gheisary, H. Zoghi-shalFree bulge hydroforming simulation was analysied to investigate the biaxial behavior of extruded aluminum tubes. A finite element model was constructed to simulate the hydroforming process and asses the influence of friction between die walls and tube, tube material properties and springback of formed tube. It was found that material hardening coefficient had the most significant influence on formability characteristics … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,863 accessesView PDFCite
