Application Summary AI generated

This standard specifies the testing method for determining the forming limit diagram (FLD) of metal tubes, which is used to evaluate the maximum deformation capacity of tubular materials before failure. It is applied in the automotive, aerospace, and general manufacturing industries for quality control and process design of tube bending, hydroforming, and other forming operations. The method is particularly relevant for engineers assessing formability in sheet metal tube products under various strain paths.
