【 摘 要 】

In sheet metal forming industry, particularly in the metallic sheet bending process, elastic recovery during unloading or in other words, the “spring-back” phenomenon, plays an important role that leads to geometric and dimensional changes in the product. In the present study, the two-layer sheet made of commercially pure copper and 304 stainless steel was fabricated by using explosive welding process and then was formed in U-shape bending process. In the study, the load was analyzed and effect of parameters such as punch tip radius, sheet thickness, friction coefficient, and mechanical properties on spring-back of the two-layer sheet was investigated using experiments and finite element simulation.
