Theoretical plasticity of textured aggregates

Rodney Hill
TL;DR: In this paper, the authors considered the plasticity of metal polycrystals with preferred orientations from a phenomenological standpoint and proved the existence of a work-equivalent function of the tensor strain-rate over any yield surface.

A general anisotropic yield criterion using bounds and a transformation weighting tensor

A.P. Karafillis, +1 more
- 01 Dec 1993 - 
TL;DR: In this paper, a gspeneral expression for the yield surface of polycrystalline materials is developed, which can describe both isotropic and anisotropic materials.

Yield function development for aluminum alloy sheets

Frédéric Barlat, +11 more
- 01 Nov 1997 - 
TL;DR: In this article, a generalized phenomenological yield description is proposed to account for the behavior of the solute strengthened aluminum alloy sheets studied in this work and the experimental yield surfaces were found to be in good agreement with the polycrystal predictions for all materials and with the phenomenological predictions for most materials.

Upper-bound anisotropic yield locus calculations assuming 〈111〉-pencil glide

Roger W Logan, +1 more
- 01 Jan 1980 - 
TL;DR: In this paper, an upper-bound model which combines a least-shear analysis and Piehler's maximum virtual work analysis was proposed to determine axisymmetric deformation.

Anisotropic ductile fracture: Part II: theory

A. Amine Benzerga, +2 more
- 06 Sep 2004 - 
TL;DR: In this article, a theory of anisotropic ductile fracture is outlined and applied to predict failure in a low alloy steel, and a rate-dependent version of the theory is employed to solve boundary value problems.

Some aspects of anisotropic plasticity in sheet metals

Roger Pearce
- 01 Dec 1968 - 
TL;DR: In this paper, the stress-strain curves of various sheet metals are determined in uniaxial and balanced baoxial tension, and it is concluded that the Hill's anisotropic theory is reasonably satisfactory for materials whose anisotropy is described with r > 1, with certain anomalies for materials with r.

Plastic flow in stabilized sheet steel

A.N. Bramley, +1 more
- 01 Feb 1966 - 
TL;DR: In this paper, experiments to assess the degree of anisotropy in stabilized sheet steel are described, where measurements of r -value are used to predict the plastic flow behavior at the centre of a circular diaphragm, which is subjected on one side to fluid pressure.
