Ductile failure analysis of high strength steel in hot forming based on micromechanical damage model
MATEC Web of Conferences, 2016 The damage evolution of high strength steel at elevated temperature is investigated by using the Gurson-Tvergaard-Needleman (GTN) model. A hybrid method integrated thermal tensile test and numerical technique is employed to identify the damage parameters.

Anisotropic ductile fracture: experiments, modeling, and numerical simulations
Journal of Materials Research and Technology, 2022 The continuous hot rolling process induces anisotropy in the plastic yield and flow and results in an anisotropic ductile fracture. In this study, experiments, including uniaxial in-plane tension tests and shear tests of butterfly specimens along ...
