According to the actual working conditions of the Vribbed belt, automobile V-ribbed belt fatigue tester machine is designed to test for the automobile engine Vribbed belt fatigue wear. Finite-element analysis software ANSYS is employed to perform finite-element analysis on fatigue testing machine load shaft, bearing, universal joint key parts of the finite-element analysis, and to analyze the m...

In studies conducted on polio survivors with late effects of poliomyelitis, new fatigue is frequently reported. The main purpose of the present study was to examine the characteristics of polio survivors reporting severe fatigue versus those reporting mild or no fatigue. From a survey among 276 representative Norwegian polio survivors, we recruited all patients with mild/no fatigue and those wi...

Steel plates with open holes are commonly used in structural assemblies. The fatigue properties of such details are influenced by bolted clamp-up and hole fabrication methods. The fracture surface, stiffness degradation and fatigue life of test specimens are investigated in detail and compared with the contemporary test data. The analysis results show that the presence of draglines greatly infl...

Usually, fatigue tests on fibre-reinforced composites are performed in uni-axial tension/tension or tension/compression fatigue [1], providing the S-N data. Although bending fatigue tests are not widely accepted as a standard, they are used a lot for research purposes [2] and they do have some important advantages [3]. In case of three-point bending fatigue, the history of bending force versus ...

introduction: now a day, resulting from life style modification and alteration, fatigue, as a consequence, is not uncommon symptom. diverse tools are available to measure fatigue status. one of which is facit fatigue scale. the facit is one of the most widely used questionnaires for screening fatigue. the questionnaire has been translated and validated? into 45 different languages, but there is...

the aim of this research is to investigate the effect of carbon fiber reinforced polymer (cfrp) composite fabric on monotonic and fatigue behaviors of reinforced concrete beams. to control the failure occurrence, a small notch was induced at the middle span in bottom surface for all of the studied rc specimens. totally 12 beams were tested from which 6 beams tested under monotonic and 6 other t...

Abstract: Introduction: Research has shown that many pregnant women in Iran do not exercise during pregnancy. However, exercise, especially endurance exercise during pregnancy, is associated with good maternal and fetal outcomes. Objective: The study aimed to examine the effect of squat exercises on fatigue and the life quality of pregnant women admitted to health centers in Hamadan City, Ira...
