Simulation and experimental study on springback deformation of duplex stainless steel heat exchanger sheet
The significant springback deformation of metal sheet makes the development of plate and frame heat exchanger extremely difficult for duplex stainless steel.In this paper,a coupled explicit to implicit finite element methods was adopted to predict springback deformation in forming processes of metal...

The significant springback deformation of metal sheet makes the development of plate and frame heat exchanger extremely difficult for duplex stainless steel.In this paper,a coupled explicit to implicit finite element methods was adopted to predict springback deformation in forming processes of metal sheet for high strength duplex stainless steel FDX27 sheet.Firstly,the explicit method was utilized to analyze the contact-based forming operation of a production stamping process.Then,an implicit method was performed to simulate the springback deformation after the forming die was removed.By using numerical simulation method,the effects of different mold radius and friction coefficients on springback deformation of FDX27 sheet were analyzed.Meanwhile,the effect of material strength property on springback deformation was studied by choosing three different sheets.Finally,different product experiments were performed to verify the accuracy of springback simulation results.The results show that the die fillet radius is not sensitive to the springback deformation height,but affects the friction coefficients remarkably.The material strength properties and hardening index N have a significant effect on the springback demormation height.The experimental results are in good agreement with the simulation results,which shows that the springback numerical analysis method is reliable and the present work provide an instruction when new material was applied on heat exchanger R＆D field. |
