Finite Element Simulation of the Bending and Springback Behavior of Advanced High Strength Steels (DP780)

In this work two bending processes are examined. The first is bending and springback in a V-die. The second is bending and springback in a “small radius” bender machine. Springback for both processes are experimentally measured for a DP780 advanced high strength steel (AHSS). The bending/springback processes are also modeled using finite element analysis (FEA), and the factors examined are; the effect of the element type (2D shell vs. 2D …
