Calculations of Stainless Steel-Aluminum Alloy Clad Forming Limit
Base on the Hosford’s higher order yield criteria, the forming limit diagram of clad was developed with M–K theory at the positive strain ratio. The relationship of forming limit with thickness ratio, thickness irregular coefficient and the exponent of yield function were analyzed. The result show that the forming limit of clad material is between those of its component materials, and increases with the rising of stainless steel thickness ratio and the thickness irregular coefficient. So the forming limit can be improved by increase the stainless steel thickness ratio and improve the surface condition of the clad materials.
