Abstract Cup-and-cone fracture in single-phase ductile metals appears to originate at holes formed by drawing away of material from non-metallic inclusions, as suggested by Tipper. In copper, the holes expand under the triaxial stresses in the neck and coalesce in a macroscopic fissure; in α iron fine cracks are formed by the stress concentrated at the

Abstract This chapter discusses the causes and effects of ductile and brittle fracture and their key differences. It describes the characteristics of ductile fracture, explaining how microvoids develop and coalesce into larger cavities that are rapidly pulled apart, leaving bowl-shaped voids or dimples on each side of the fracture ...

In this chapter, the main characteristics of brittle and ductile fractures, caused by single load application, are described. Each section begins with a description of the macroscopic features that allow for identification of brittle and ductile fractures, and continues with the description of the mechanisms of formation of the fractographic features ...

Ductile Fracture of Rapidly Expanding Rings
Journal of Applied Mechanics, 1983Heterogeneous plastic deformation (necking) of thin ductile rings given an initial outward impulse is described in terms of the ordinary differential equations of thermoplasticity and the partial differential equations of mass and momentum conservation in one spatial dimension (circumference) and time.

Fracture Of Metals Part II : Ductile Fracture
2001Ductile fracture results from the nucleation, growth and coalescence of cavities. Nucleation starts from inclusions. Mechanics of inclusions is used to write the nucleation criterion. The growth rate can be derived from the deformation of a cavity in a plastic or viscous material. Plastic potentials of a porous plastic solid yields the rate of increase
