dc.description.abstractThis research explores an extended method of fracture mechanics to determine the parameters of the Johnson Cook and GISSMO models. The primary objective of the optimization process and iterative finite element method (FEM) was to identify optimised modelling parameters suitable for specimens with different shapes to predict the failure behaviour of dual-phase steels (DP), specifically DP600 and DP800 steels. Numerous experimental tests were conducted on these DP steels, which mainly consist of ferrite and martensite phases. The specimens underwent deformation at three different tensile velocities. To determine the flow curves, a Simplified Johnson-Cook model (MAT_SJC_098) was employed, while the Johnson-Cook model (MAT_JC_015) was used to identify failure, and a combined JC-GISSMO model was used to determine damage. The numerical simulation results were then compared with the experimental results. In conclusion, all modelling methods used in this research yielded the desired results.
