Accumulation and Healing of Damage during Plastic Metal Forming Simulation and Experiment
Based on the analysis of experimental data on measuring metal density under plastic deformation, an adaptive model of damage accumulation, which takes into account the transient processes of damage variation with changes in loading conditions, has been formulated. The analysis of damage in the process of cold closed-die forging of a lid-type steel blank being taken as an example, the applicability of the model to the prediction of fracture in the optimization of industrial metal forming technologies has been demonstrated.
