Özet: In sheet metal forming processes, local necking and fracture failures limit sheet metal form to desired shape. Computer models have been developed to estimate the material behavior in these processes. Material parameters are needed to represent the real forming processes. These parameters are generally obtained from tensile test and forming limit diagram. Diagrams that specify formability limit are forming limit diagram shows limit strains and forming limit stress diagram shows limit stresses.    In literature, it is remarked that while forming limit diagram cannot estimate the failures for complex and gradual forming processes, forming limit stress diagram can successfully.
