In this paper, the original and shear-modified GTN ductile fracture criteria are utilized to
investigate the fracture behavior of the AA6061-T6 aluminum alloy sheet during the stretch …

The effectiveness of a ductile fracture model in accurately predicting fracture initiation has
been demonstrated. In this study, we concentrate on applying the ductile fracture model to …

For icebreakers to navigate polar routes, the ability to break through ice sheet is extremely
important. To quantify this, technology that can estimate the mechanical behaviors of ice and …

Accurately identifying the unknown parameters of the Gurson-Tvergaard-Needleman (GTN)
damage model is essential to better understand the damage behavior of materials and …

Background Reliably calibrated criteria are needed for an accurate prediction of fracture of
various components. However, there is not always a sufficient amount of material available …

Ductile fracture criteria are crucial in the application of elastoplastic materials like advanced
high-strength steels, particularly due to their tendency to fail without significant localized …
