Title: Finite Element Simulation Of Magnesium AZ31 Alloy Sheet In Warm Hydroforming

Abstract

Hydroforming of magnesium (Mg) alloy sheet metal offers the possibility to form geometrically complex sheet metal parts that are applicable within automotive and electronic industry etc. However, due to the limited formability of Mg alloy at ambient temperature hydroforming of Mg alloy sheet metal has to be conducted at elevated temperature. In the present study an experimental warm hydroforming process using a low melting point alloy as forming medium is presented and on the basis of this a 2D thermo-mechanical finite element model is setup in order to analyze the temperature distribution in the Mg alloy workpiece during forming. The results show that the temperature in the workpiece is nearly uniform and nearly identical to the temperature of the forming medium.
