Localized necking of sheet metals subject to out-of-plane punch stretching is studied.
Attention is directed to the effects of various constitutive laws on the development of …

For elastic-plastic sheets under biaxial stretching localized necking is investigated assuming
that the material follows a kinematic hardening rule. The investigation is mainly based on the …

The effects of void nucleation occurring during the deformation history on forming limit
curves are considered for both in-plane and punch stretching employing a constitutive …

In the present paper the diffuse and localized necking models according to Swift [Swift, HW,
1952. Plastic instability under plane stress, Journal of the Mechanics and Physics of Solids …

A rational approach to the localized necking problem was given by Storen and Rice [J.
Mech. Phys. Solids 23 (1975) 421] but this approach is limited to the description of …

Criteria for diffuse and local necking in sheet metals stretched over a hemispherical punch
have been developed. During stretching, a peak develops in the distribution of strain across …

A theoretical and numerical analysis of the formation of a localized neck in a biaxially
stretched sheet is presented. A time-independent constitutive law is assumed to be …

A plane stress constitutive relation for rigid-plastic sheets under biaxial stretching is
presented, in which the yield surface expansion models the behaviour of a solid carrying a …

The role of void growth in triggering local necking in biaxially stretched sheets is
investigated. A recently proposed constitutive equation for porous plastic materials is …

T he necking of an elastic-plastic circular plate under uniform radial tensile loading is
investigated both within the framework of the three-dimensional theory and within the …
