Sheet Metal Bend Characteristics When sheet metal is formed into a bend, the metal on the inside of the bend is compressed and the material on the outside of the bend is stretched around an imaginary line along the thickness of the material sometimes call the nutral line or as Solid Edge refers to it as the PZL= Plastic Zone Length. The plastic zone size r p, that is, the length of the strip yielded is given by the assumption that the stress intensity factors K I and K II = 0 at the tip of the effective crack of a eff = a+ r p. The approximate solution is obtained by superimposing the stress intensity factors of case ( i) and case ( ii) shown in Fig. com is your online source for industrial metal supply.
