dc.description.abstract | The various fracture models based on different mechanical concepts have been proposed to predict ductile fracture behavior. The fracture tests on EH36 ship building steel were carried out by Park et al.(2019), where different specimen geometries, central hole, shear, and notched tensile specimen, were used to identify Hosford-Coulomb model. In this study, the experiments results in previous study are compared with seven ductile fracture model: Johnson-Cook, Cockcroft-Latham-Oh, Bai-Wierzbicki, modified Mohr-Coulomb, Lou-Huh, Maximum shear stress, and Hosford-Coulomb. The effect of loading path was considered using linear damage accumulation law. The flow stress was defined using Swift-Voce combined constitutive model. The histories of stress triaxiality and calibrating fracture model parameters. The fracture model was compared in terms of the stress triaxiality, Lode angle parameter, and fracture strain space. | - |
