Analysis of tube hydroforming in a square cross-sectional die
Yeong-Maw Hwang,Wen-Chih Chen +1 more
TL;DR: In this paper, a mathematical model considering sliding friction between the tube and die is proposed to explore the plastic deformation behavior of the tubes during a hydraulic expansion process in a square cross-sectional die.

Analysis and finite element simulation of tube expansion in a rectangular cross-sectional die
Y-M Hwang,W-C Chen +1 more
TL;DR: In this paper, a simple analytical expression was proposed to estimate the forming pressure of a tube during the hydraulic expansion process in a rectangular cross-sectional die, and the effects of the friction coefficient between the die and the tube upon the thickness variations at certain positions during expansion and the thickness distribu...

Large strain inelastic behaviour of cylindrical tubes
E. Chater,Kenneth W. Neale +1 more
TL;DR: In this article, the finite strain behavior of thin-walled circular cylinders fixed at their ends and subjected to uniform internal pressure is examined, and the influence of constitutive properties and tube geometry on maximum pressure and localized necking instabilities is determined through finite element computations for selected types of anisotropy.
Journal ArticleDOI
Analysis of elastic and plastic strains for internally pressurized cylinders
TL;DR: In this article, theoretical considerations and experiments on elastic and plastic strains in rotational internally pressurised shells with rigid bottoms are presented. Butler et al. showed that the results obtained with the shell bulging can be a basis for work on a method allowing the control of the wall thickness while forming tubular elements in industry.

Bulge formation during internal pressure testing of viscoplastic tubes
TL;DR: In this paper, the burst test is used to identify a variety of properties of a tubular sample, including the constitutive behavior of the material and the pressure capacity of the tube, and it is shown that for tubes with viscoplastic behavior, controlled plastic strain can continue throughout the entire sample long after passing the point of maximum pressure.

Plastic instability under plane stress
TL;DR: In this paper, conditions for instability of plastic strain under plane stress for a material conforming to the Mises-Hencky yield condition and strain-hardening according to a unique relationship between root-mean-square values of shear stress (q) and incremental strain (δψ).
Journal ArticleDOI
Tensile plastic instability under complex stress
TL;DR: In this article, the authors considered the problem of changing from a known mode of deformation determined by imposed loads and load rates to a second unknown mode determined by the current rate of strain hardening, analogous to necking in the tensile test.

Tensile instability of thin-walled cylinders of finite length
TL;DR: In this article, an analytical solution for the bursting conditions of thin-walled cylinders with finite length diameter ratios is presented based on the Ludwik strain-hardening law, the Mises effective stress-strain criterion and the total deformation theory of plastic flow.

The ultimate strength of thin-walled shells and circular diaphragms subjected to hydrostatic pressure
TL;DR: In this article, the ultimate strength of thin-walled cylinders, spherical shells and circular diaphragms subjected to hydrostatic pressure is investigated for materials whose strain-hardening characteristics can be fitted by the empirical equation \gs = A(B + \g3)n.
Journal ArticleDOI
Plastic instability of cylindrical pressure vessels of finite length
TL;DR: In this article, the authors extended the known solution for the plastic instability failure of an infinite cylell unerinternal pressure to shells of finite length, where the ends of the shell are constrained in such a manner as to prevent radial motion but to permit axial displacements.
