DETERMINATION OF SIMULATION PARAMETERS FOR FRACTURE CRITERION IN SHEARING

Original language description

The prediction of a fracture in forming processes was analyzed strongly in recent years. A number of material tests for determining a fracture criterion were carried out. This study examines a fracture criterion on the basis of tension and torsion tests. The correct value of the fracture criterion is influenced by forces and fracture areas. Normalized Cockcroft-Latham and Oyane fracture criteria were used for comparison of a simulation and an experiment. Obtained values of the fracture criteria were consequently used in a simulation of the plate shearing. The description of the whole process of the plate shearing covers not only the initiation of a fracture but also the growth of the fracture until the material parts are separated. This issue was solved by means of two numerical methods, the softening and the element deletion. The simulations were performed using DEFORM software based on the finite element method.
