Finite Element Simulation of Deep Drawing of Steel - Aluminium Tailor - Welded Blanks

Abstract

In the automotive and aerospace industries, the need for lightweight products is absolutely necessary. By combining between the strength and lightweight material usingTailor Welded Blank(TWB), the need can be achieved.Aluminium has the tendency to flow more than steel due to the lower density and weaker.Independence blank holder allows the application of different force on steel and aluminium in the forming process.The blank sheet flow can be controlled by different blank holder force (BHF).The promising materials are Steel and Aluminium alloy thatare formed into single blank sheet.The purpose of this numerical study is to demonstrate that dissimilar strength Steel-Al TWB can be subjected to deep drawing operations successfully, using optimum process parameters in the Finite Element (FE) simulation.The simulation indicate that Steel-Al TWB can produce deep drawing components.
