摘要：
Formability of two-layer metallic sheet is constrained by plastic instability and localized necking. Forming limit diagram (FLD) is an accepted measure of sheet metal formability. The formability of two-layer sheets depends on the material properties of their components such as strain hardening exponent, strain rate sensitivity coefficient, stiffness coefficient, and grain size. In this paper, the effects of the mentioned parameters on the FLD of two-layer sheets are investigated with a theoretical model which has been verified with an experimental approach. The results show that the forming limit of two-layer sheet lies between the forming limits of its components depends on their material properties.
