The paper OS0815 describes how to determine the Gurson parameters based on the experimental observation. In this paper by using the same fracture tests of the notched round bar specimens the Gurson parameters were determined based on the optimization tool and the fracture behavior of the same flat plate test as in the OS0815 paper was estimated. The load-COD and COA-COD curves of the plate specimen from the Gurson model analyses show good agreement with the experimental result. Additionally applicability of the strain criteria of ASME Section VIII Division 2 Part 5 was investigated comparing with experimental results of the notched tensile specimens. The estimated rupture displacement shows various margins dependent on the selected criterion. More experimental confirmation seems to be needed for the criteria.
