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 …

The following general problem is considered: Elements of a solid body deform appreciably
only when the local stresses satisfy a certain relation; the material properties are otherwise …

Exactly 80 years ago1), in one little known engineering journal, appeared a paper by a
young scientist–“Właściwa praca odkształcenia jako miara wytężenia materiału”[Specific …

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 …

A new method of limit analysis of structures is introduced whereby a continuous structure
made of a perfectly plastic material is replaced by a discrete mathematical model. The stress …

The general problem of stability under dead loading is treated for a body of any shape, the
material being workhardening and rigid-plastic. It is shown that when the plastic potential …

Several classes of mathematical theories of plasticity for work-hardening materials are
surveyed and their advantages, disadvantages, and agreement with experiment discussed …

Reissued in the Oxford Classic Texts in the Physical Sciences series, and first published in
1950, this important and classic book presents a mathematical theory of plastic materials …

This book is intended to be an introduction to the fundamentals as well as to the most
important engineering applications of the theory of plasticity. This branch of the mechanics of …

The “plastic methods” are concerned with the conditions of failure of statically indeterminate
structures of ductile metal, mild steel in particular. Continuous beams and frames of mild …
