The fundamental definitions of work-hardening and perfect plasticity have far reaching
implications with respect to uniqueness of solution for elastic-plastic bodies. Satisfaction of …

The purpose of this note is to point out the severe restriction imposed on possible stress-
strain relations by a mathematical formulation of the concepts of work hardening and ideal …

Within the framework of a purely mechanical theory for finitely deforming elastic-plastic
materials, it has been shown previously (1, 2) that strain-hardening behaviour may be …

Since the pioneering work of Tresca in 1864, many talented engineers and applied
mathematicians have contribuited to the theory of metal plasticity, developing an elegant …

The workhardening and linearity hypotheses introduced by Drucker are logically equivalent
to the hypotheses of the existence of the plastic potential and of its identity with tlie yield …

It is well known that the use of Tresca's yield condition frequently leads to a simpler system
of equations for the stresses in a plastic solid than the use of the yield condition of Mises …

The definitions given previously for work-hardening and perfect plasticity are broadened to
cover viscous effects. As before, the system considered is isothermal and includes both the …

The analysis of combined loadings in the plastic range, very important both from the
theoretical and from the engineering viewpoint, is one of the more difficult branches of the …

Introduction. Drucker's[1] definition of work-hardening has had a significant influence on the
development of stress-strain relations in the mathematical theory of plasticity. Also …

The yield point of a plastic-rigid body is defined as the moment when deformation first
becomes possible as the load is increased. The practical significance of the yield-point load …
