Description
Single Point Incremental Forming (SPIF) is an innovative forming technique in which a stylus forming tool incrementally deforms a blank sheet into the final shape. The deformation mechanism is quite different compared to traditional forming processes. Moreover, fracture prediction remains a significant challenge. In the current study, a hybrid experimental–numerical approach was conducted to calibrate the Johnson–Cook damage model for a high-strength aluminum alloy. The calibrated model serves as a sophisticated tool for capturing the onset of fracture in SPIF. Both isotropic and anisotropic material behaviors were investigated. The results indicate that the anisotropic model is capable of predicting fracture in terms of location and depth with a relative error of $7.74\%$ compared to the experimental results.
