Paper Title:
Springback Simulation in Stretch Bending of Aluminum Extrusions Using Static Implicit and Dynamic Explicit FE Codes
  Abstract

First stretch bending process of aluminium extrusions given by Norwegian scholars is simulated by using revised model proposed in the paper. That maximum die force calculated is closer to experiment than Norwegian scholars’ one demonstrates that the revised model is rather accurate in forming simulation and lays the foundation for later springback simulation. Then springback is simulated by using dynamic explicit and static implicit FE codes, respectively. The influences on cross-sectional distortion and springback of two codes are compared. It is shown that dynamic explicit FE code can predict cross-sectional distortion accurately and static implicit FE code overestimates it. Neither of two codes can predict springback accurately. Dynamic explicit FE code overestimates it and static implicit one FE code underestimates it.
