经过简短的介绍，本书分为三个主要部分，分别涉及“机械行为的结构方面”、“非弹性变形力学”和“非弹性行为力学的应用”。该部门的目标是结合物理和工程方法，全面展示超出弹性范围的应变材料的机械行为。因此，它必须尝试提出物理学、物理冶金学、化学（在有限程度上）和工程学领域的当前观点。对于单个作者来说，这是一个以权威方式涵盖的广阔领域，但本书的质量必须根据其完成的相对成功程度来评估。首先考虑物理观点，必须承认前两章与许多早期金属物理书籍中的内容非常相似。这并不意外，只能被解释为批评，因为重点可能有所不同。例如，有人可能会质疑，第一章中为玻尔原子模型和类似的基本物理主题提供的空间是否可能不会花在处理偏离完美晶格的影响以及金相结构对非弹性性能的影响的章节上。本书的第二部分也是最长的部分更清楚地展示了工程师的方法，但这部分包含许多有趣的描述性插曲。关于蠕变和松弛的部分似乎对所涉及的现象进行了特别清晰的描述，而关于加工硬化和断裂的部分则包含一些发人深省的建议，但并非所有这些都是正统的。最后，早期的想法得到了发展并应用于一些特定的案例，本书最后有一章介绍了机械测试的重要性，这是最有趣和有用的。这本书包含许多刺激和有趣的材料，但并非都成功地实现了其目标。部分原因是目标很高，部分原因是分析性和描述性内容交替的呈现方法并不总是有利于轻松阅读。尽管如此，作者成功地在他所积累的材料中留下了自己的观点，并且结果是一本非常值得一读的书，尽管读者可能会发现自己在许多方面与作者不同。使用本书作为其通常领域之外的信息指南的工程师应将其视为起点，并倾向于查阅整本书中给出的许多参考文献中的一些。
After a short introduction, this book falls into three main parts, dealing respectively with " the Structural Aspects of Mechanical Behaviour," " the Mechanics of Inelastic Deformation" and "Application of the Mechanics of Inelastic Behaviour." The object of this division is to present a complete picture of the mechanical behaviour of materials strained beyond the elastic range, combining the physical and engineering approaches. Of necessity, therefore, it must attempt to present current views in the fields of physics, physical metallurgy, chemistry (to a limited extent) and engineering. This is a wide field for a single author to cover in an authoritative manner, but the quality of the book must be assessed on the relative success with which it is done. Considering the physical point of view first, it must be confessed that the first two chapters are much the same as has been written in a number of earlier books on metal physics. This is not unexpected and is only to be construed as criticism in that the emphasis might have been placed rather differently. For example it might be questioned whether the space given to Bohr's model of the atom and similar basically physical subjects in Chapter I might not have been spent on a lengthier development of the sections dealing with the effects of departure from a perfect crystal lattice, and of metallographic structures on the inelastic properties. The second and longest part of the book shows more clearly the approach of the engineer but this section contains a number of interesting descriptive interludes. The section on creep and relaxation seems a particularly clear description of the phenomena involved, while those on work hardening and fracture contain some thought-provoking suggestions, not all of which are orthodox. Finally, the earlier ideas are developed and applied to some particular cases and the book concludes with a chapter on the significance of mechanical testing which is most interesting and useful. The book contains much stimulating and interesting material but it is not uniformly successful in achieving its objects. In part this is because the aim is high and in part because the method of presentation with alternations of analytical and descriptive matter is not always conducive to easy reading. Nevertheless, the author succeeds in impressing his own point of view on the material he has accumulated and the result is a volume which is well worth reading, although the reader may find himself differing from the author on many points. The engineer using the book as a guide to information outside his usual field should regard it as a starting point and be inclined to consult some of the many references which are given throughout the book.
