“…For simulating the press anvil and the edger tools (rollers), analytical rigid bodies are employed. Coulomb friction model with friction coefficient of 0.35 is used for modeling the contact between the workpiece and tools both in the vertical rolling and SP processes (Chun et al, 2003(Chun et al, , 2005Shangwu et al, 2000aShangwu et al, ,b, 2001Shangwu et al, , 2003.…”
