Q. In stretch forming, forming limit curve (FLC) is defined as a locus of all the limit strains in different strain paths of the sheet metal.

 in stretch metal forming process, the forming limit curve (flc) provides quantification about the formability of sheet metal, which basically gives the details about the quality of material. the forming limit curve (flc) is generally defined as a locus of all the limit strains in different strain paths like deep drawing and biaxial stretching, of the sheet metal.
