A numerical approach for the modelling of forming limits in hot incremental forming of AZ31 magnesium alloy

Abstract Magnesium alloys, because of their good specific material strength, can be considered attractive by different industry fields, as the aerospace and automotive one. However, use is limited poor formability at room temperature. In this research, a numerical approach proposed in order to determine an analytical expression hot incremental forming processes. The model was developed using commercial software ABAQUS/Explicit. Johnson-Cook used, validated through experimental measurements carried out ARAMIS system. Different geometries were with temperature varying range 25–400 °C wall angle 35–60°. An fracture limit, function temperature, established finally tested geometry assess validity.
