چکیده
|
5xxx series of aluminum alloys are a category of novel alloys suitable for construction of ship hulls and the topside structures of offshore platforms. within different 5xxx aluminum alloys, aa5083 is of great importance which is extensively used in ship construction industry. in the present study, formability of aa5083-h111 aluminum alloy is investigated at room temperature using uni-axial tensile tests and hydraulic bulge tests. tensile tests were performed to evaluate material anisotropy in different directions with respect to rolling direction. anisotropy coefficients were then used to correct flow stress curves obtained by balanced biaxial bulge tests. moreover, flow stress curves obtained from both tests were separately introduced to an explicit commercial finite element code. comparisons showed that numerical simulation carried out in this study stand in according with empirical results.
