Abstract: This paper describes a damage-based formability analysis for tailor-welded blanks (TWBs) using an anisotropic damage model and damage criterion for localized necking. The damage model and criterion are coupled into finite element code to simulate the stamping process of JIS G3141 steel TWBs. Forming limit strains are computed based on the damage criterion for different values of strain ratio. The computed limit strains are found to be satisfactory as compared with the measured values, thus validating the anisotropic damage model and the failure criterion of TWBs at localized necking.
