A micromechanically motivated uncoupled model for ductile fracture prediction [PDF]
工程科学学报, 2017 This paper is a contribution to the ductile fracture prediction by the proposal of a new uncoupled ductile fracture criterion. In the new criterion, two typical void deformation models were carefully considered, with the plastic strain increment regarded

Plasticity and Ductile Fracture of High-Strength Steel Center-Holed Plates under Tension
Metals, 2023 The mechanical behavior of bolted connections in high-strength (HS) steel structures is a matter of concern, since the less ductility compared to mild steels may affect the load transfer and stress distribution of bolted connections.

Chinese Journal of Mechanical Engineering, 2021 Ductile fracture of metal often occurs in the plastic forming process of parts. The establishment of ductile fracture criterion can effectively guide the selection of process parameters and avoid ductile fracture of parts during machining. The 3D ductile

An Anisotropic Damage Model for Prediction of Ductile Fracture during Cold-Forging
Metals, 2022 Researchers have formulated equations of ductile fracture to simulate and predict defects in cold-forged parts, e.g., the Cockcroft–Latham criterion. However, these equations are not applicable to certain cases of fracture in forged products.

Ductile Fracture Prediction in Hole Hemming of Aluminum and Magnesium Sheets
Metals, 2023 The present work proposes a suitable approach for predicting ductile fracture in a new joining process by plastic deformation called hole hemming. This process creates a combined form- and force-fit joint and enables the joining of lightweight materials ...
