摘要

1978年，罗德·史密斯（Rod Smith）与基思·米勒（Keith Miller）合著了一篇关于缺口疲劳极限的论文。在Rod对我们这个领域做出的许多有价值的贡献中，这篇论文对我来说是最突出的。我相信它是优秀科学的一个极好的例子，为一个过去（现在仍然）以复杂性为特征的领域带来了清晰。接下来，我将介绍这篇论文，特别是其中使用的一种图表，我建议将其命名为史密斯-米勒图。这张图在工程设计中有很大的实际用途，用于评估应力集中特征，也适用于法医失效分析和本科教学，Rod Smith在这些领域也很擅长。

When is a notch a Crack? Analysis of an early paper by Rod Smith and Keith Miller

In 1978 Rod Smith published a paper, co-authored by Keith Miller, on the subject of notch fatigue limits. Of the many valuable contributions which Rod made to our field, this paper stands out for me. I believe it to be an excellent example of good science, bringing clarity to a field which was (and still is) characterized by complexity. In what follows I introduce the paper and in particular a type of plot used in it, which I propose to name the Smith-Miller diagram. This diagram is of great practical use in engineering design for the assessment of stress concentration features and also has applications in forensic failure analysis and in undergraduate teaching, areas in which Rod Smith also excelled.

期刊介绍： Theoretical and Applied Fracture Mechanics'' aims & scopes have been re-designed to cover both the theoretical, applied, and numerical aspects associated with those cracking related phenomena taking place, at a micro-, meso-, and macroscopic level, in materials/components/structures of any kind. The journal aims to cover the cracking/mechanical behaviour of materials/components/structures in those situations involving both time-independent and time-dependent system of external forces/moments (such as, for instance, quasi-static, impulsive, impact, blasting, creep, contact, and fatigue loading). Since, under the above circumstances, the mechanical behaviour of cracked materials/components/structures is also affected by the environmental conditions, the journal would consider also those theoretical/experimental research works investigating the effect of external variables such as, for instance, the effect of corrosive environments as well as of high/low-temperature.
