Computational approach using Johnson-Cook model on dual phase steel
In this research, two different hypo-eutectoid steels with different carbon content and alloying elements were made into samples with dual phase ferrite martensite microstructure. Their morphology and the mechanical properties were then compared. Computational model varying the ferrite percentage wa...

| Summary: | In this research, two different hypo-eutectoid steels with different carbon content and alloying elements were made into samples with dual phase ferrite martensite microstructure. Their morphology and the mechanical properties were then compared. Computational model varying the ferrite percentage was also proposed. The model adopts the failure rule of Johnson–Cook’s. The result shows that the difference in mechanical property was not only due to the variation of the ferrite parts in them but also due to the shapes of the constituents. It tends to follow the continuum mechanics rule. It is also concluded that modeling using two-dimensional approach is sufficient to estimate the properties of the dual phase structure. |
