Abstract : This report describes the findings of a working party formed by the Fatigue Research Advisory Group (FRAG). The main aims of the working party were to review specimens commonly used to generate fatigue and fracture data and to recommend specimens to be used in the future for a wide range of test purposes. This report defines a selected number of laboratory specimens which are recommended for future use in fatigue and fracture testing of metallic materials and joint configurations. It also defines a small group of core specimens which should be preferentially chosen when assessing the fatigue and fracture qualities of a particular material or of a particular structural feature. Guidelines are given on dimensional changes which may be needed for specific requirements. Advice is also given on specimen manufacture and assembly methods.
