Abstract

Forming limit testing is widely used to characterize materials for use in forming operations. Subset based Digital Image Correlation (DIC) has become a common method used in research laboratories to measure the forming limit strain fields, but no consistent method exists for forming limit determination from these data. In this work, we apply a design of experiments approach along with Finite Element Analyses to exercise potential experimental measurement requirements numerically (especially varying expected image resolutions and frame rates) to quantifying the sensitivities of various proposed forming limit analysis methods to changes in experimental setup and DIC processing parameters. The main goal is to determine the appropriate hardware to produce benchmark experimental data, and possibly highlight which forming limit analysis methods may be either overly sensitive, or preferably insensitive, to subjective processing decisions.
