Commentary :
Generally in metal forming processes, fracture is synonymous with deficient products, unexpected costs and potential catastrophes, and therefore hopefully prevented during the design stage of a product in order to ensure its integrity and durability. Nevertheless, for a few manufacturing techniques the fracture phenomenon is the driving step of the entire process. This is the case for the sheet metal blanking method where the quality of the
final product is directly linked to the resulting shape of the sheared edge. Therefore, the numerical prediction of the failure initiation and further propagation plays an important role in order to ensure the optimal set of process parameters and to fulfill the required product features, especially in mass production.
