Investigation of Ridging in Ferritic Stainless Steel Using Crystal Plasticity Finite Element Method
The ridging problem in ferritic stainless steel is well known and unsolved for more than two decades. Ferritic stainless steel (FSS) sheets exhibit ridging parallel to the rolling direction when subjected to tension or deep drawing. The origin of ridging has not been clearly explained yet. Most models suggested before are too simplified and underestimate the influence of neighboring grains. In this study, we simulate the ridging phenomenon using the crystal plasticity finite element method (CPFEM). We test the previous models with CPFEM and investigate the relations between orientations and ridging by simulating a more realistic case using EBSD results.
