Abstract
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.
