WebJan 28, 2024 · In this study, the Hosford-Coulomb (HC) model, one of the advanced fracture models, is implemented to study the shear quality during the shear-cutting process for DP980 sheets. A hybrid experimental–numerical approach is adopted for the accurate calibration of the HC fracture model. WebApr 14, 2024 · The calibrated GISSMO fracture card for 780 XG3 TM steel was then validated in simulations of wedge-bend tests, two notched tensile tests and axial crash tests of octagonal, 12-sided and 16-sided components. The predicted fracture locations, displacement at fracture and force-displacement curves agreed well with the test results. disney world orlando 50th anniversary https://steve-es.com

WebThe Mohr-Coulomb criterion assumes that failure is controlled by the maximum shear stress and that this failure shear stress depends on the normal stress. This can be represented by plotting Mohr's circle for states of stress at failure in terms of the maximum and minimum principal stresses.

WebThe theoretical framework employed in this thesis is based on two fracture models to predict the material behavior: The Modified Mohr-Coulomb (MMC) and the Hosford-Coulomb (HC). Furthermore, a hybrid and a direct calibration method are used to get the models parameters. WebA comprehensive combined hybrid numerical-experimental program is executed on three advanced high strength steels (DP980, CP980 and CP1180) with the objective of validating (1) the hypothesis of a positive strain rate effect on the ductility under biaxial tension, as well as (2) the Hosford–Coulomb model assumptions with regards to the Lode ...
