Triaxial state of stress is usually generated in the necked zone because of neck geometry,
and as a consequence proper correction of true tensile stress–strain curve after necking is …

The stress–strain behavior of sheet metal is commonly evaluated by tensile test. However,
the true stress–strain curve is restricted up to uniform elongation of the material. Usually …

The exact stress–strain curve can be directly identified from uniaxial tension experiments up
to the point of onset of diffuse necking. To gain insight into the post-necking hardening …

An iterative correction procedure using 3D finite element analysis (FEA) was carried out to
determine more accurately the effective true stress–true strain curves of aluminum, copper …

A procedure for determining the stress–strain curve including post-necking strain is
proposed. Hourglass type specimens were used for tensile tests, and the stress–strain …

Background Measuring true stress–strain curve over a large-strain-range is essential to
understand mechanical behavior and simulate non-linear plastic deformation. The digital …

For metallic materials, standard uniaxial tensile tests with round bar specimens or flat
specimens only provide accurate equivalent stress–strain curve before diffuse necking …

The paper presents an experimental evaluation of deformation of flat samples during
uniaxial tensile testing, including uniform deformation and post-necking phases. The authors …

Quasi-static tensile test is a common, yet fundamental, experiment in determining the
mechanical properties of materials. Often, the determination of the equivalent stress–strain …

In post-necking tension of cylindrical specimen, the stress corrections based on the current
analytical models have relatively significant errors at large strains. In this study, the …
