抄録

In this paper, the spring back in the plastic bending of a single clad sheet metal was treated theoretically and experimentally in the same way as in that of a double clad sheet metal previously reported. In consideration of the variations of the stress states in loading due to the work conditions and the differences among the mechanical properties of the clad and base metal of the clad sheet metals, eighteen equations for the spring back were obtained theoretically. The results of the spring back calculations agree well with the experimental results. Then, the effect of the clad ratios etc. on the spring back is made clear. Brass, Phosphor-Bronze and Nickel-Silver clad in Silver were used as the tested materials.
