Hi all, I wanted to know if actual springback after forming depends on sheet rolling direction. As anisotropy coefficients (r0, r45 and r90) affect thickness reduction, I think they must be important in springback analysis but during routine process (as defined in related tutorial) which is performing springback analysis following an incremental forming simulation, they are ignored at all. Am I wrong? Thanks in advance.
Hi all, 1- As sheet metal resistance to thinning is not the same in different directions (which is the subject of Lankford coefficients), how can we define FLD curve without considering rolling direction? 2- In Radioss one-step forming simulation in which we define r0, r45 and r90 during material definition, is there a pre-defined sheet rolling direction? Is it X axis or what? Thanks in advance.
