The premature failure of a material from the exposure to the combined action of corrosion and cyclic stress is called 'Corrosion Fatigue.' This type of failure is generally encountered in pump shafts, heat exchanger tubes, rotors, steam turbine blades, aircraft wheels, boiler and steel equipment....
Thermal fatigue behaviour of hot-work tool steels: heat check nucleation and growth Cyclic thermal loading causes thermal gradients near the loaded surfaces, which are responsible for the development of cyclic strains and mechanical stress... R Ebner,S Marsoner,I Siller,... - 《International ...
However, under heat, reboxetine decreases, whereas bupropion increases performance, thus suggesting that the thermoregulatory system may have an important influence on exercise performance. The CNS, via a central neurotransmitter, produces various excitatory and inhibitory inputs on the spinal motoneurons...
This study investigates the effects of the material properties and the fatigue behaviors in the SM490A material weld specimens, which are made by same method of railway vehicle structure, due to the heat-treatment and the grinding. In the fatigue behavior, the heat treatment affects the fatigue ...
Results uniformly reveal a positive impact of HIPing for all three materials compared to their other conditions. Depending on annealing temperature and the consequent impact on the microstructure, a heat treatment causes positive and negative effect for aluminum series. A temperature to low in order ...
where frequency of stressing is low enough and the samples are small enough that heat generation is not an important factor in failure and, to a lesser extent, the case where heat generation due to large samples and high frequency load application builds up temperatures which contribute to ...
Previous studies have suggested that the anti-inflammatory amino acid glutamine may reduce subjective fatigue, enhance physiological responses to heat stress, and potentially improve work performance32. Conclusions Fatigue is a prevalent and pressing issue among medical security personnel operating in closed...
Fatigue-crack growth tests were conducted on three heats of wrought material plus one heat of weldment at temperatures of 24, 316, 427, 538, and 593/sup 0/C. The effects of heat-to-heat variations, crack orientation, and thermal aging were studied. In addition, stress ratio effects were ...
Stochastic Response Analysis of Mooring Systems with Emphasis on Frequency Domain Analysis of Fatigue Due to Wide Band Response Processes, Ph. D. Thesis, Norwegian University of Science and Technology, Norway. Google Scholar Hearle, J. W. S., Hobbs, R. E., Overington, M. S. and Banfield...
In an actual deployment, the part most likely experiences dynamic loading at different rates; however, the elementary focus is on the number of cycles rather than the frequency, especially in the absence of accelerating environmental conditions, such as swelling due to moisture or radiation and ...
