Hereby, the forming limits of an as-received aluminum alloy (AA5052-O) sheet are evaluated under a basic quasi-static-dynamic loading condition. The plane-strain deformation, which in quasi......
Laser forming thin aluminum sheetsLI Li-qun(李俐群), CHEN Yan-bin(陈彦宾), LIN Shang-yang(林尚扬)(State Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 15001, China)Abstract:Laser forming is a flexible forming process that forms sheet metal by means of laser-induced stresses instead of by means of external force. With the rapid development of laser......
