TL;DR: In this article, the effects of anisotropy and temperature on cyclic deformation and fatigue behavior of two short glass fiber reinforced polymer composites were investigated and a fatigue life estimation model was also presented which correlates data for different temperatures, fiber orientations, and stress ratios.

TL;DR: In this article, the authors discuss the effect of range of stress, rest periods, and complete flow of history on the problem of detecting and eliminating false positives in the field of forensic investigations.
Abstract: THE EFFECT OF RANGE OF STRESS, REST PERIODS AND COMPLEX LOAD HISTORIES ON THE PROBLEM OF FATIGUE IS DISCUSSED. THE CONCLUSION IS DRAWN THAT THE FATIGUE LIVES OF CONCRETE SUBJECT TO FIELD LOADING CONDITIONS SEEM SIGNIFICANTLY GREATER THAN CONVENTIONAL FATIGUE TESTS INDICATE. THE PASTE AGGREGATE INTERFACE IS SUGGESTED AS THE CRITICAL POINT FROM WHICH THE CRACKS LEADING TO FATIGUE FAILURE EMANATE. THE STATE OF KNOWLEDGE UP TO SEPTEMBER 1965 IS SUMMARIZED, AND AREAS FOR FURTHER RESEARCH SUGGESTED. /RRL/

TL;DR: In this article, the strength of Inconel 718 under rotary bending fatigue was investigated at room temperature, 300, 500 and 600°C in air, and the effect of temperature on the fatigue strength was examined in terms of the initiation and early growth behaviour of a small crack.
Abstract: The strength of Inconel 718 under rotary bending fatigue is investigated at room temperature, 300, 500 and 600 °C in air. It is found that in the long-life region, the fatigue strength of a plain specimen is much higher at elevated temperatures than at room temperature, though the static strength decreases with the increase in temperature. The effect of temperature on the fatigue strength is examined in terms of the initiation and early growth behaviour of a small crack. The results are discussed in relation to the competition between the softening of the nickel matrix (γ phase) and the surface oxidation at elevated temperatures.

TL;DR: In this paper, the authors developed a new methodology to generate a constant life diagram (CLD) for metallic materials, based on assumptions of Haigh diagram and artificial neural networks, using the probabilistic Stussi fatigue S-N fields.
