The forming defects of parts mainly include fracture, springback, thermal expansion, and rough surface during electric hot incremental forming, in which the springback expansion directly affects dimensional accuracy parts. In this paper, combined optimization process parameters unsupported distances was proposed to control sheet process. predictive model major errors established through respons...

Since the deformation region involves interaction of electric-thermal-force coupling in electric hot incremental sheet forming, numerical simulation forming process is unusually difficult. Currently, thermal-force method adopted to simulate approximately whole process, and Joule heating effect often ignored. Therefore, especially significant for prediction accuracy process. In this paper, a nov...
