Calculations of forming limit diagrams

Metallurgical Transactions A, 1990
The right-hand side of the forming limit diagram (FLD) was calculated using a Marciniak-Kuczynski analysis with a nonquadratic anisotropic yield criterion. Effects of changing the strain-hardening exponent, n, strain-rate exponent, m, strain ratio, R, stress exponent in the anisotropic yield criterion, a, and the inhomogeneity factor, f, were explored.

Non-Traditional Forming Limit Diagrams for Incremental Forming

Advanced Materials Research, 2005
Although not standard, Forming Limit Diagrams, FLD’s, are used throughout the automotive industry as a preliminary tool to determine if a sheet metal forming process is capable of forming a good part. FLD’s show a limited range of strains on the diagram; typically the range is 0 to 1 on the major strain axis.
