概述了塑性理论的几个关键方面的发展和现状，作为对这门学科的新手或没有集中参与的人的文学指导。在这些广博的文献中，只有一小部分被引用。特别注意弹性理论和初始各向同性的作用，这种影响常常是鼓舞人心的，但更多的是具有误导性。对于金属加工过程或延性工程结构和设备的分析或设计，在最强大的计算机上使用所需的应力-应变关系的简单性，与以非常粗略的细节模拟真实行为所需的巨大复杂性形成鲜明对比。试图正确地放置各种传统的和非传统的旧的和当前的表示法。还探索了在原子、位错或单晶水平与宏观或连续水平之间传递结果的适用机制。
The development and the present state of a few key aspects of the theory of plasticity are sketched as a guide to the literature for those new to or not centrally involved in the subject. Only a small fraction of this extensive literature is cited. Special attention is paid to the frequently inspirational but more often misleading influence of the theory of elasticity and the role of initial isotropy. The required simplicity of stress-strain relations to be usable with the most powerful of computers, for the analysis or design of metalworking processes or of ductile engineering structures and devices, is contrasted with the enormous complexity needed to model real behavior in quite crude detail. An attempt is made to place in perspective a variety of older and current representations, both conventional and unconventional. Applicable regimes of transference of results between the atomic, dislocation, or single crystal level and the macroscopic or continuum level also are explored.
