The research presents experimental and numerical identification of the effect of dynamic effects on the sheet-metal blanking process. A novel laboratory blanking apparatus has been presented, offering a wide range of experiments with great repeatibility and controlled variation of process parameters. From the blanking experiment, yield and ultimate stresses in the out-of-plane direction are identified, and from the partial and sequential experiments, material damage, modelled by the Lemaitre damage model. Effect of material anisotropy in the in-plane direction on the out-of-plane characteristics is assesed. A numerical code, based on the extended finite element method and explicit central difference method, for two-dimensional modelling of elasto-plastic contact problems is presented, using damage accumulation up to fracture and crack propagation through the critically damaged area.
