In this investigation, we study experimentally the evolution of both the deformation and the
stress during the necking process of a thin metal sheet subject to uniaxial tension. The …

A one-dimensional finite element program has been developed to study the effects of inertia
on necking instability in a round bar under tension. An elastic-viscoplastic constitutive law is …

A s part of a study of failure of plates at built-in supports, modes of plane strain failure under
increasing bending with constant tension are calculated for an elastic, power-law plastic …

The tensile test is a standard technique of mechanical testing suitable for ductile materials,
which can provide quantitative measures of the intrinsic mechanical properties, such as …

The two conditions for stable necking, treated as a bifurcation of stress path, are derived.
The anisotropic material considered is one for which the plastic work increment= σ¯ de¯ …

The influence of material inertia on neck development in a notched round bar is analyzed
numerically. Dynamic axisymmetric calculations are carried out for isotropically hardening …

To more accurately capture the onset of localized necking and obtain necking limit strains,
this paper proposes a method of detecting the onset of localized necking in the Marciniak …

This work is concerned with the modeling of the necking phenomenon in metallic tension
members using a non-linear theory of elasto-plastic rods with deformable cross section. The …

The static elastoplastic characterization of metals consists of the determination, by way of
experimental tensile tests, of the curve expressing the equivalent von Mises stress as a …

Applying two theories in plasticity (flow theory and a modified deformation theory), the
necking of a cylindrical bar in uniaxial tension is analysed. The development of finite strain …
