This paper investigates the accuracy and reliability of nominal stresses, hot-spot stresses, effective notch stresses, notch-stress intensity factors (N-SIFs) and material length scale parameters in estimating fatigue lifetime of aluminium welded joints.
To the Editor: As a former hot-line counselor for the Parental Stress Hot Line, a statewide, 24-hour anonymous hot line for parents in Massachusetts, I am always deeply saddened when I read of parents believing that corporal punishment is necessary to discipline children.
Plots correlating maximum in-plane shear stress and distance to the nearest grain boundary demonstrate that stress "hot spots" tend to accumulate near grain boundaries.
The proposed modeling framework can be useful for providing an overview of the water security within the watershed and to identify water stress (hot spots) regions within the river basin.
Due to exposure to many environmental constraints, some local varieties of the tropical japonica rice developed high adaptability to drought stress, hot and dry climatic conditions of regions in Latin America and Africa.
No major abiotic stresses (drought, hot and dry winds) were encountered.
For instance, animal fitness is often limited by fluctuations in the availability of basic nutrients as well as by abiotic stresses (too hot, too cold, or too dry climate, low oxygen, etc).
Stress analysis methods based on nominal stress, structural hot spot stress and effective notch stress are discussed.
By expressing the critical distance evolution as a function of the hydrostatic stress gradient operating next to the stress hot-spot, dispersion was reduced below 5%.
In this context the application of the structural stress (hot-spot), notch stress, notch strain and crack-propagation concepts are discussed through the example of K-nodes used in energetic offshore constructions like oil platforms or wind power plants, presenting the state of the art.
Different approaches – the nominal stress, structural hot spot stress and notch stress approach – to analyse the fatigue strength of welded structures made from wrought aluminium alloys were studied.
