Stability on the Yield Surface
1991It is proved that, if plastic deformation is unrestrained, the yield surface has to be equipotential for free energy. On the other hand, if plastic deformation is isochoric, then the intersections of the yield surface with the planes at constant volume must be equipotential.

Yield surface linearization in elastoplastic analysis
Computers & Structures, 1987A method for the historical elastoplastic analysis of plane frames under the assumption of small deformation theory is presented. Interaction of bending moment and axial force is taken into account. A major feature of the procedure lies in the piecewise linearization of the convex nonlinear yield surface, thereby guaranteeing the satisfaction of both ...

Analytical Representation of Polycrystal Yield Surfaces
1991A new yield function of the form \( f\left( {{S_i}} \right) = {\sum\limits_S^N {\left| {P_i^S\,{S_i}} \right|}^{{h + 1}}}/W_s^h \) is proposed to describe the yield surface of textured polycrystals. The parameters of this function can be derived from the rate of plastic work obtained from polycrystal models.

A family of smooth yield surfaces
Mechanics Research Communications, 1985The smooth yield surface introduced by \textit{P. V. Lade} and \textit{J. M. Duncan} [Proc. ASCE SM 99, 793 ff. (1973)] for the modeling of soils is shown to belong to a family of surfaces which also includes as a special case a recently introduced surface [the author, ibid.

Yield surfaces in local strain theory
Polymer Mechanics, 1974The initial yield surfaces for biaxial tension and combined tension and torsion are determined on the basis of the local strain theory. The limit surfaces of the resultant stress on a local plane in tension (torsion) are obtained. A plastic strain probability factor is introduced and its values are calculated for various loading paths.
