dc.description.abstract | This technical note presents the effect of two options to determine model parameters of a strain-based damage model on ductile tearing simulation. Notched bar tensile test data are used to determine the parameters in the first option, whereas only smooth bar tensile data are needed in the second one. In this investigation, four material data are considered. By comparing the simulation results with experimental data, it can be shown that it is difficult to simulate both crack initiation and crack growth well using the first option. However, with the second option, good agreement can be achieved in the prediction of both crack initiation and crack growth in all cases. A possible reason for overestimating crack growth using the first option is discussed. | - |
