Numerical Investigation of Reverse Redrawing Process Using a Non Associated Flow Rule

Deep drawing process is commonly used to produce particular components like aerospace and automotive structural parts. Based on the drawing ratio, it can be performed in a single or a multiple-stage drawing. Due the complexity of this process, finite element simulations are considered as a powerful tool for the both reasons: reducing times and costs, and improving quality and productivity. The current study is conducted to evaluate the performance and the capability of a non associated flow rule (NAFR) approach on numerical results during reverse re-drawing process of DDQ mild steel metal. The adopted model is implemented on ABAQUS software using user interface material subroutine (VUMAT).
