    Maximum Contact Stress To Prevent Clamp Marks

    According to Matweb for AISI 1018 Steel, cold drawn, the tensile yield strength is 53,700 psi and the ultimate tensile strength is 63,800 psi. So, if I keep my hertzian contact stress below 1.8 x 53,700 psi = 96,660 psi, I will not see any surface defects or plastic deformation from the v-block...

The round bar needs to be clamped while the end of the bar is chamfered and end faced. However, the round bar can not have any marks on it. I can calculate...
