Uniaxial tensile tests were conducted at room temperature, 100° C and 150° C, for obtaining
necking-corrected stress–strain curves until fracture. The necking correction is based on …

The true stress–strain curve has a significant role in the analysis of deformation in theoretical
plasticity and numerical simulations. Because of the triaxial state of stress in the neck zone …

To make comparison between classic necking stress solution Bridgman formula and
ChenChi formula, the difference of necking surface profile assumptions in these two …

To obtain the material true constitutive relation of tensile specimens after necking, we
proposed an experimental‐numerical combined method (ENM) based on the simple tension …

In this study, the necking three-dimensional strain on minimum cross-section at room
temperature was performed experimentally and analytically. A modified strain assumption …

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 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 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 …

Correction of the stress–strain curve in the strained specimens after necking is one of the
remarkable issues in mechanical engineering. The corrected curve strain–stress is needed …

The goal in this research is to evaluate the correct true stress-true strain curve after local
necking up to a true strain of 1.0. To achieve this goal, a smooth round tension test was …
