In macro-scaled plastic deformation processes, viz., macroforming, the so-called ductile
fracture has been extensively studied in terms of the physics, mechanisms, affecting factors …

Workability is a measure of the extent of deformation that a powder metallurgy materials can
withstand prior to fracture occurred in the forming or upsetting processes. Ductile fracture is …

One major issue is accurate prediction and effective control of crack defects, which is one of
the key scientific problems in developing high-quality rotor forgings. As a result, an …

It is well known that once plastic deformation reaches a certain limit, metal materials may
undergo ductile fracture, which will affect the workability of engineering materials. The …

To predict accurately the forming limit in sheet metal forming, the combination of FE
simulation with tension tests is adopted in this paper to determine the material constants p …

Hot compression tests were conducted on Ti40 burn resistant titanium alloy in the
temperature range of 900–1 100° C and strain rate range of 0.01–10 s− 1 to investigate its …

Mechanical degradation and ductile failure in metal forming operations can be successfully
modelled using Continuum Damage Mechanics. In addition to elastic–plastic deformations …

Formability is the measure of deformity a workpiece can endure from the created stresses
inside the substance before the crack event. The investigation of the formability of powder …

The Knowledge of metal flow and strain at fracture is most importance to the plastic damage
in metal forming. Failure in metal working usually occurs as ductile fracture, rarely as brittle …

Equal channel angular pressing (ECAP) is an important process for producing ultra fine
grains in bulk metallic materials by means of severe plastic deformation. Workability of …
