Deformation behavior of laminated sheet metals is estimated by the upper bound method based on Hill’s plasticity theory for anisotropic materials. The r-value and the stress-strain curve are theoretically derived for the laminated sheet metals whose component metals are combined at arbitrary angles to the rolling direction. Tension tests of the laminated sheet metals which are made by bonding in combinations of mild steel, brass, and aluminum sheet metals are carried out. The experimental results are compared with the theoretical ones. They are in good agreement.
