Ductile Tearing or Plastic Collapse?

Abstract Ductile fracture is characterized by a large amount of deformation. Two mechanisms may lead to ductile failure: local tearing appear in front stress concentration region like crack or geometry changes weak part the structure can induce global collapse structure. For cracks such as those considered Leak Before Break studies, analyses and net-section criteria have been used. The present paper examines link between these two for through-wall cracked pipe under bending concludes that transition from depends not only on material properties but also geometrical parameters. reference approach promising predicting transition, provided transferability issue j-resistance curve has solved.
