Abstract:

An experimental and numerical investigation is carried out in order to determine a material deformation of a blanking process. A highly localized, large strain distribution during the process at the last stage of a complete martial separation, has influence on the final surface quality product. Commonly using method in simulation of the blanking process is based on numerical approach. However, due to the large plastic element deformation is highly recommended to use remeshing procedure and other estimation solutions to simulate the last stage. To verify the final results and theoretical model other method are required. The paper present some implementation of experimental investigation in the field of displacement and strain measurement using a digital image correlation technique (DIC). The authors presents an experimental results of 1 mm thick specimen at the planar blanking process, where different clearances were used in the designed, fully automated apparatus. Finally, the experimental results were compared to the FEM simulation model with a good agreement.
