Research ArticleOpen accessPhrase in the titleTwist Springback Measurement of Autonomous Underwater Vehicle Propeller Blade Based on Profile DeviationAhmad Baharuddin Abdullah, Mohd Sapuan Salit, Zahurin Samad et al.Geometrical defects that are attributable to springback are among the major defects induced by the sheet metal forming process. Such defects are critical for sections with varying thickness, such as Autonomous Underwater Vehicle (AUV) propeller blades. In this study, the springback in the twist-bending of an AA6061 propeller blade was quantified by comparing the targeted and manufactured profiles obtained using … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 31 May 2013 · 7,383 accessesView PDF Cite
