A theoretical basis is established for analysis of finite deformation of metals. The observation
that finite deformation of such elastoplastic materials may be viewed as a process rather …

The present paper is concerned with numerical simulations of large deformation and
necking behavior of axisymmetric tensile specimens. In particular, an efficient framework for …

We present a finite element approach for analyzing tensile tests using the rigid-plastic finite
element method. To predict the necking in the tensile test, a mechanically perfect, simple …

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 …

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 …

Necking is a bifurcation phenomenon observed in round bars under tensile loading and has
been investigated in numbers of papers. In the present work, it is modeled within the …

Due to its simplicity in instrumentation and data analysis, uniaxial tensile tests are commonly
used for determining the plastic stress-strain relation of a sheet metal. However, the tensile …

Tensile necking in anisotropic bars is analyzed in the spirit of PW Bridgman's treatment of
the isotropic case. Anisotropic plastic flow causes an initially axisymmetric bar to develop an …

Some issues arising in the formulation of finite strain plasticity problems are discussed. One
issue concerns the formulation of finite deformation elastic-plastic constitutive relations for …

Computational strategies relevant to finite strain elasto-plastic problems are discussed and
the necessity for both a sound theoretical framework and numerically consistent linearisation …
